it's been a while since I've done math, and i know most of this stuff but have some particular rust issues
in problems such as this one:
(x^2-3x-4) - (x^3+x^2+x+5)
what do I do? Obviously is not multiplying because of that - sign. do I have to solve the first one, which can be done easily, and then just substact the whole thing??
also in another problem I ended up with this:
I know I can contnue factoring but how exactly do I do it?
(3x- ) (3x+ )
Im not sure what to do when the x^2 has a number in front. do those 3 have to multiply the numbers I use in the blank space??
and this problem tells me to find the quotient and remainder
problem is: 4x^3-3x^3+x+1 divided by x+2
so my question is, how do I even start with this? do I literally divide it or does the x+2 flip to the top and I just multiply the rest??
