i need to know if i did this problem right
4y(y^2-8y+6) -3(2y^3-5y^2+2) :shock:
i got:
-2y^3-17y^2+24y-6 :shock:
is that correct? if not, what is the answer and how do you get it?
thanks
b/c my math teacher is an idiot so i never really know if im doing anything right....and she will tell you things wrong, and she will say stuff is wrong when its right....
basically, according to her, 2+2=22
