Smart Strategies for Polynomial Division

Stop doing polynomial division the hard way because you are absolutely wasting your time.

When you need to check if something is a factor, like this x plus 3 situation,

do not start dividing. Just use the Remainder Theorem. You literally just plug in negative

3 into the function. If the answer comes out to zero, boom, it is a factor.

It is the ultimate math cheat code. And for that scary fourth-degree equation at the bottom?

Don't panic. It is just a hidden quadratic in disguise. Factor it like normal, don't forget your

imaginary numbers, and you are done. Work smarter, not harder.
