Best FACTORING Hack EVER! 

Use to be good in Algebra I loved multiplying,dividing and factoring polynomials. Now that I’ve been married 40 years plus, I’m trying to refresh ny menory about it all. Looked at the best factoring hack you put out and stopped the vidio to figure the three case 1 videos and felt excited I figured then all correctly when I reatarted the video watching your answers. Thanks so much for putting these videos out.

3/29 @ 5"49 pm Great advice on note taking. I've been there, like you!

I have never seen this wonderful way before. It is really easy way to solve polynomial problems thanks teacher I don't have much to say because math is not my thing

Thank you very helpful İf you don't have time Skip to <a href="#" class="seekto" data-time="442">7:22</a>

tnx very simple and easy tutorials

Ay bro you're the real MVP I been watching videos all morning but you definitely helped me understand it better

Thank you very much teacher. I ferl more ready now to take the exam.

Thank you.

thanks a mil. I needed you when I was 14. and 15. and in college...ad infinitum. thanks a Mil.

What a great video! Thanks you tube maths man.

John do you have any good resources for teaching computer science?

Thanks tor uploading this!

Great Hack! and no need to solve the complicated quadratic solution.

without remembering i see a 2 ans a 7 in the right side xexp2 is single so x and or another is 14 so we have sign diff between 7 and 2 that brings us to - 5x in this case 2 - 7 is -5 lets see (x+2)(x-7) i expand i get the problem that was a good tip previous.....

This is a great video to help kids visualize it.

Hi John, can you show us how to derive the quadratic equation? Thank you!

😇thank you thank you,very helpful

Aaasrrrrgghhh Over four minutes of intro and selling before you get to the content. I guess some people appreciate that, but I don’t. Good content when you can finally get to it

(x + 2)(x -7)

Factors of 14 = (2,7) (1,14) choose (2,7) -14 = (-2,7) (2,-7) choose (2,-7) since middle term is -5x (X-7)(x+2) Hence X=7 and -2 I can't remember how I learn this. Is it from my teachers or by observation or from earlier algebra topic? I think it is from from the earlier algebra topic: FACTORING. And Observation. Math is a ladder. If you cannot understand step of the ladder 2, you cannot understand step of the ladder 5. Math gets more difficult after Algebra and Trigo. But these two subjects are the foundation of higher math: analytic Geometry, Calculus, Advance Math and Differential Equations.

Thankyou

its also called the box method

<a href="#" class="seekto" data-time="230">3:50</a> he gets to the point

X^2-5x-14=? Is this about factoring or solving a quadratic equation by factoring?

What about 3x^2 + 6x + 10? AFAICT, it cannot be solved using part 2 method - no real roots?

What would you use this to solve?

Love

Taking my hiset math and reading tomorrow hope that i pass

<a href="#" class="seekto" data-time="232">3:52</a> he gets to the hacks.

There is a shortcut for case 1 Find the factors of -14 that when added together equals -5 -7,+2 (x-7)(x+2)=X^2-5x-14

(x-7(x+2)=0, x=7or -2

I see the relationship 2 and 7 Then it's (x+2)*(x-7) 2x-7x=-5x 2*-7=-14

I couldn't find your solution by scanning (too much talk for me), but I got the answer in my head: (X-7) (x+2). Right?

🙏🏼

What about the 3X^2 +6X +10? You missed it out 😭 So i worked it out for you 😋 Were it only 3X^2 +6X +3 it would become (√3X +√3)^2 but that leaves the remainder 7. To include this remainder requires that it would become (√3X + √3 +√7i)(√3X + √3 -√7i) As the additional+/- √7i (the 7 being the remainder) is the only way to increase the final value 3 to 10 without affecting the 6X as it would make both + and - (√3X)(√7i) which cancel each other out, and similarly on the final number, a + & - (√3)(√7i) also cancelling out, but it would also make an additional term, a (√7i)(-√7i) which equals - -7, which is the same as +7 thus raising the 3 to a 10 Presuming you know that 'i' is √-1

equate to zero, X = 7 ; X = -2 : ( X - 7)( X + 2 ) = 0

Me and my 6th grader are doing things like case 2 but with fractions squared and fractions not squared

X=-2 or 7

👏👏👏

X=7

(x-7)(x+5)

He is teaching the rules. Why and how to solve a math problem.

Reverse FOIL method

This is the reason why people hate math the teachers like hearing their own voice instead to go on directly to the explanations that they need

-7 and +2 are factors. X=7,-2

XY=-14 X+Y=-5

Vid starts at <a href="#" class="seekto" data-time="230">3:50</a>

X plus 7 x minus 2

When you get to the actual business these are good helps. However, there is soooooooooo much just talking and repeating non important things and the backward, forward, backward, forward that it all gets muddled up and confusing. If it were just a step by step with needed explanations these lessons and hacks would be much easier.

I’m lost😢

Maybe I missed it. But this hack only works for real factors.

X^2-5x-14= 1527(x+1x-5) x+2x-7)

It works very good Thank you 😀

Easy: (x-7)(x+2) Just do it by inspection. You can write the answer straight down. You don't need any "hacks". And also it is "problem" not "prawm".

3 mins in and he is still talking about things unrelated to this problem.

🆒🆒🆒👍👍👍👋👋👋

This is not a factoring "hack". It's just another way to do factoring. Sheesh.

very annoying. You neverget to your solution for 4 minutes. I'll find someone who doesn't advertize their site so long.

To much talk ...

A 4 minute commercial before getting to the subject. You talk too much. I'll never click on one of your videos again.

Get on with it. 8 minutes before you explain anything!

You know, I understand that note taking is very important and all, but do you have to repeat the same stuff about over and over again on every single youtube vid you do?!?!? seriously?!?

Sorry to spoil this party, but... Hack?!?!?!?!? 20 minutes for a 20 seconds video about something u learn in 8-9th grade? And 20 minutes without touching trinomial cases in which "a" is not equal to 1??? What the hekk is going on here?

I appreciate your tutorials but too much unnecessary talking

Your process needs to be simplified rather than going through so many steps and you need to concentrate on one problem and not confuse how to solve one problem with another problem.
