Who's Grade-9 here?🎉❤

Who's here who don't like this subject yet still watching .. 😆

up coming g9 here, nag-aadvance learning

Pov: nag aadvance learning ka na, bago pa mahuli ang lahat 😂

okay,this is literally a good teacher...I UNDERSTAND ITT!!thx to you,GON

Can you make another like this but with the checking

Thank youuu, i watched tons of yt math tutorials but this is the only one that helped. You're a good teacher! I hope I won't forget this until next schoolyear (yes im an upcoming grade 9 and i've been studying advanced) goodluck to me i guess. Anyways, thanks alot! God bless! :)

For no. 6 X²+5x+6=0 (X+3) (x+2) since the two factors of 6 are 3 and 2 in which if you sum up this two the answer would be positive 5. X+3=0 x+2=0 X=-3 x-2(these are the roots of the equation) .. Cause if you transpose positive 3 and positive 2 of course the answer would be negative.

#6) ASSIGNMENT REPORT (X1=-3, X2=-2)

Preparing myself for Grade 9, because I know Grade 9 will probably be the hardest year of highschool😢

6. X^2 + 5X +6 = 0 6 could be like 3(2) where if we add we can get the sum of 5. (X+3) (X+2) = 0 x+3=0 | x+2=0 x= -3 | x= -2

But how about a number we canot develop ? Exemple : X^2 - 5X - 7= 0

Checking po pls 😔

Good morning po sir Taga Grade 9 - Bernoulli po ako Si Ma.Floritalyn Artuz

thank you po! i'm a slow learner and minsan rin lutang ako sa school lalo kapag math time na so hindi talaga ako nakakasabay but with this i was able to understand how to factor ^^

6, x²+5x+6=0 (x+3)(x-2) 6 = 3•2 3+2 = 5 [X1 = -3] [X2 = 2]

thank you this was relly helpfull for my upcoming gr9

teacher gon pano po pag x2 + 6x = 16 paano po yan same lang po ba ng solution sa no.1?

X1=_6,x2=1

wala po talaga akong maintindihan sa mathematics 😭

pa correct po if it is (×+2)(×+3) next we are going to equate then we have ×=-2 and x=-3 as the answer??? correct me if am wrong.

X 7 or x -4

Find, it hard, very complicated 😆

It’s easy Q6 answer is x=-3 and x=-2 x2+5x+6=0 (x+3)(x+2)=0 x+3=0 , x+2=0 x=-3 , x=-2 This is the answer.

hi po! pwede po bang next upload nyo is tungkol sa factorial, di ko kasi ma gets yon e. Tysm!!

for no 6 X=1 X=-6

Sir gon pano po pag z² - 18x + 81= 0 Nahihirapan po kasi aq ei

Please why did you not use the 3 when solving problem three?

Plz Don't write x as multiplication sign write x as curved one. students gets confused with x and multiplication sign

I still dont understand math😢

X=-2. X=3 tama ba ako sir?

Name: Mikaela Juliana Alagad Grade 9 Einstein Sir. Paul Evan Mornaol My answer in no. 6 is X^2 + 5x + 6 = 0 (X + 2) (X + 3) = 0 X + 2=0 X+3= 0 X=-2 X=-3

THis is how I solved the no.. 3 & the no..

Sir pwede po bang kahit baliktarin ung x-3 at x-5

For Number 4: We can also factor the 3x² - 75 = 0 into (3x-15)(x+5) = 0 : Same result as yours. Thank you

Whoever is here, listen carefully because tomorrow you have a quiz

Sir ito po yung akin x1=-3 and x2=2 Galing niyo po mag turo🥲

Thanks very much sir I can now solve

This is much better than the other videos ive watch recently 😩

What if namn sir pag 11r+15=2r²?

No, I think you should write that : x.x - 5.x = 0 / x ( x - 5 ) = 0 / x = 0 or x - 5 = 0 / x = 0 or x = 5 ......the problem is the way for students can learn easily.

Paano po kung hindi po 0 Yung equal nya? Kase po ung saken 8 po ung equal x²+7x=8

Orada ikinci bir iks yoktur. Cambazlik yapmayınız. Bakınız ikinci ve daha yüksek derecedeki denklemlerin çözümü.huseyin Ergül

X1=3 X2=2

Alam ko yan sir

Sir puwede ka ba mag upload grade 9 curriculum math 1st -4th q

Sir, the answer in #4 is correct but I doubt with your computation, as far as I remember we cannot just disregard that 3 in the equation. Its better to show that 3x² - 75 is equal to (3x - 15)(x + 5) = 0. In this factor we can show the proper computation.

In that case of item number 3, before I use the extracting square root method, I transpose the constant number first and my answer is x=±7.

(x+7)(x-4

Ans. for item 6. X1=3 X2=2

dis is very helpful thankkk uuu

X=-3 X=-2

You make the concept look so difficult

Thanks you know the next class or grade 10 maths

I think the solution for 6 is x¹=-3 and x²=-2

Sir pwede ba gamitin yung formula na x= -b/a sa number 2?

Sir with checking

(X+7)(x-4)

6= 3 •-2 (x+3)(x-2) Set both sides by 0 x+3=0. |. x-2=0 x¹=-3. |. x²=2 Correct me if im wrong po🥰

paano po gawin ang checking?

Division by factored quadratics/polynomials seems to give lots of people problems. 8in³÷2in(2in²+2in²)=? 1? Or 16in⁴?

Paano naman kapag 9x²-16=0 ??

The assignment of number 6). X1=-3|X2=-2 hopefully we are perfect I love this because I learn how to solve quadratic equation love u sir hopefully more video and I believe

di ko pa din gets 😭😭💔😭💔💔😭💔😭😭💔😭💔😭💔

Excellent explanation please keep it up

I have a question what if its x+5 = 0 do i subtract it?

Grade 9 - Bernoulli Ma.Floritalyn Artuz My Answer in Number 6: X² + 5x + 6 = 0 ( x + 2 ) ( x + 3 ) = 0 x + 2 = 0 | x + 3 = 0 x = -2 | x = -3

Teacher gon this is correct or wrong x=2)(x=-3

May test kami bukas HAHAHAHAH thank youuu!

Ik its been like 2 years but i just turned grade 9 so the answer for number 6 is x1 = 5 and x2 = -3

Thank you very much sir ang galinh nyu po mag explain 💙❤️

Sana po makapasa ako sa 1st quiz inulit ulit ko pa pong panoorin yung video nyo😊

Can I ask kung paano yung -5x3= -2? Bakit e add po? Diba e subtract kasi unlike signs. Subtract naman yung answer pero na gulo yung ulo ko kasi sinabi mo e add, sir. HAHAHA.

6.) X² + 5× + 6 = 0 (× + 3) (x - 2) = 0 ×¹ = -3 | x² = -2

Could you use Chinese and English both together explain it.because my kids doesn’t understand English

Kyla Joy Pontiga, 9 - Bernoulli po sir 😁

👍🏿👍🏿👍🏿

Not this guys explaining 10x better than my own teacher 😭😭😭

Mahihirapan ka talaga intindihin Kung basics plang di mo Alam😔

Ceredon, Princess Marielle A. 9-Bernoulli

7x³-9x²-76=0 Pls answer it's so hard it's my assignment

On question 1 sir what if positive number ung value ng b dadagdagan parin po ba or ba bawasan naman po? Please answer po

SALAMAT PO!

Sir pass ko na po assignment ko: X² + 5x + 6 = 0 (x + 2) (x + 3) = 0 I got this because 2 + 3 is equal to 5, and 2 x 3 is equal to 6. x + 2 = 0 | x + 3 = 0 x¹= -2 | x² = -3

Thank you for. Your tutored

You are a gift! Thank you for doing this!

My answer to x^2+5x+6=0 is (x+3)(x+2)=0 x sub 1 = -3 x sub 2 = -2

Sir not quadratic po ba ang x+4x=0 ang alam ko po kase hindi sya quadratic

sa example madali lang pero pag exam/activity NAPAKAHIRAP HAHAHAHHAHAHAH

X²+5x+6=0 (X+6) (x-1) x+6=0 x-1=0

boyagggg, exam na borikat

nag send po ako message sa fb page mo po. may question lang ako how to get 95% of a certain number in fast way

How po sa checking in this X=-1/9 9x²-12x-4=0

X=-3 and X=2 po ang answer kuya?

If it is equal to zero no need to answer because it's already equal to zero!

Malate, 9- Einstein po

Salamat po sir lagi kasi ako lutang sa math subject eh. Madali lang pala

u missed another step......replace the value of x to test if the answer is correct...

x1 = -3 x2= 2
