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.

I’m in one of your classes and I found your videos to be very helpful. I was looking stuff up for extra information and came across this, had no idea it was you at first but recognized your method and then your profile picture. Appreciate you posting these.

Thank you very helpful

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

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

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.

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

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

[oldschoollew]

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

[kimberlyanderson]

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

[fredancajas]

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

[enriquelucero]

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

[jidejonesentertainment]

nice concept. Please what app are you using to display in this class?

[johnlakin]

What a great video! Thanks you tube maths man.

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

[Newjedi-gl]

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

[blackmaleb]

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

[MichaelClark-uwex]

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

This is a great video to help kids visualize it.

[quabledistocficklepo]

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?
