Good q for learning but its reverse many times not true. Like if we take root we consider only + ve...???

Great

Why teacher not use easy Solution '

(x+y)xy = 1/2 1/y + 1/x = 1/2

What a legend.

For ever, short, simple and to the point unlike some of the other videos.❤

Yeah but how do I do it without writing all the possibilities

Carry on.

Why do.

Largest area enclosed with 4000 meters fencing material is 2,000,000 square meters.

Many people are smarter than me but only few can explain something to a dumb person like me. You're one of the few sir!

Fantastic

Hi,Sir! How old are you?

Nice!

Quality🎉

Ein Genie...😅

So 2 is the only positive integer and the two other solutions are complex solutions?

Hey sir, should I divide the 2 over 20?

Negative cash x negative cash = positive savings 😂

C. -5 I think is the answer!

I hate maths but finally a question on YT seemed easy to me 😅 thanks sir

I think they should stop watering down the curriculum, and return algebra 2 back to what it was, put back trigonometry as a full year class and get rid off precalculus, which is really algebra 2. The way it is now is terrible! I have been tutoring math and science for over 20 years, and the students know LESS than when I first started tutoring and certainly less than when I was in school. This is why we are getting farther and farther behind the rest of the world in math and science - lowering standards and not raising them. AND WHILE I AM ON MY RANT, GET CALCULATORS OUT OF MATH CLASSES AND THE SAT. THE CALCULATOR CAN DO MATH, MANY STUDENTS CANNOT!!!

Why not before?

Thank you very much, I am currently studying for an ASVAB Test and this was a much needed lesson. I will continue to educate myself through your channel.

Special experience what is this

A principal square root cannot be negative.

is the plus minus sign only applicable to square roots?

Did it by substituting x² for z and using quadratic formula to solve. Then take the square root of the solutions and you get the same solutions

The inverse cosine function only exists in quadrants 1 and 2 which means 240° is outside the range of the inverse cosine function since it’s in quadrant 3

Area=4sqrt(6)

No, 3i doesn’t equal -3

Fucking genius on my screen

C

X<=13.5

Me in the last one: 3 < x

Proving the formula for the vertex: the vertex is where the derivative of a function is zero and quadratic functions are written in the form of ax^2+bx+c and if we differentiate with respect to X we get 2ax+b=0 we rearrange for X to get the X-coordinate by taking away b from both sides so 2ax=-b then we divide both sides by 2a to get X=-b/2a

Undefined, this is the principal root which only asks for the positive number. It would be positive or negative if you put a plus-minus sign before it. E.g: sqrt(36)=6 but plus-minus sqrt(36)= plus-minus 6

You’re welcome

X=+-3, +-1

There’s a quadratic inside the quadratic

I smiled after watching this video. It's like a heavy burden has just been lifted off me. Thanks

Arithmetic progression

thank you.

That is exactly what I win Atlanta jackpot
