Question 128388: multiply (5x-3)(x^3-5x+2)
Answer by apachemexican1(64)   (Show Source):
You can put this solution on YOUR website! (5x-3)(x^3-5x+2)
use foil to solve this problem
first multiply
5x*x^3=5x^4
5x*-5x=-25x^2
5x*2=10x
now you have half of the solution
5x^4-25x^2+10x
next multiply
-3*x^3=-3x^3
-3*-5x=15x
-3*2=-6
now you have the other half of the solution
now combine them both and look for like terms
5x^4-25x^2+10x-3x^3+15x-6
add like terms (15x-10x)
5x^4-3x^3-25x^2+5x-6
that is your answer
good luck!
