Question

multiply the polynomials using the distributive property and combine like terms:
(x+7)(-3x+2)

Answer 1

First, multiply x by everything in the second parenthesis, aka "distribute" it. Then do the same with the 7. I trust you know how to combine the like terms after you've done that.

Answer 2

x*-3x=-3x^2
x*2=2x
7*-3x=-21x
7*2=14
-3x^2+2x-21x+14\[-3x^2-19x+14\]
