anyone wanna help me?
How do you factor something that's like
x^3 - 4x^2 + 5x - 2

thats number 44 and I don't know how to do 44, 46, or 48

Oh crap. I know I learned how to do this last year but I can't remember how. Everything I ever learned leaked out of my head after graduation. Sorry.

ok...
I forgot this completing the square nonsense
so how do you complete something like
x^2 + 3x + 1

and something about the binomial theorem and you get this crazy "n" variable that i'm really confused with

so use the binomial theorem to simplify
(a + b)^7

I feel so dumb doing this work.
