Couldn't understand when my math teacher explained it for 40 minutes, and I get it from this 2 minute video. Thank you so much

[superkidsvadodara]

Wow, that was such an easy method for factorising 4 terms. Thank you so much for sharing this video.

[TheStalkingEmu]

This video's a lifesaver man. I'm taking precalculus and I'm trying to remember how to factor polynomials. Thank you so much!

[ailurii]

Thank you. Thank you, thank you, a million times *thank you*.

[JosephAMuniz-hmjh]

Thank you for the video. I'm just now, at 36, finally grasping the concepts of intermediate algebra. There's absolutely no better feeling I've experienced than the one I receive after spending an hour struggling with a problem, and then to finally -- as if like magic, suddenly discover/realize the steps needed to achieve the solution! Factoring polynomials was always where I called it quits. Now it is finally clicking!!! Albeit, I've come to a place in my life where I've built up the discipline to sit for several hours a day and work on math... But yeah... Thanks for the quick and concise refresh on FBG. :)

HOW TF YOU TEACH THIS IN 2 MINUTES AND MAKE ME UNDERSTAND IT WHAT MATHIMATICAL POWERS DO YOU HAVE!!!

[josephshaff]

Never mind I got it w/ Synthetic Div, . (x-1) and then factor the trinomial left.

[codebreakerx]

What if the binomials don’t match, do you just leave it as it is?

[RustInsiding]

I did not know you did math now Mr. Sins

[liaqatkhan]

In reality, I do not how to factor accourding to the time. If you do not mind, than upload the next video about this!

[aroyce]

how did he get the 2x-1 on the first equation?

[tristan_]

How did you factored (2x³-x²)?
I'm bad at Math

[xdaltacc]

who knew sigma from overwatch was a math teacher

[vanessahsieh]

Why'd you add the negative sign on the 6

[nyahh]

Maybe I’m just slow but I still don’t understand 😕
