AnnZ [28]

Answer:

A.30x3-3x2-24x+9

Step-by-step explanation

1. Separate the terms in g(x). (6x) (-3)

2. Distribute by multiplying each term in f(x) by (6x).

   (6x)(5x2+2x-3)=30x3+12x2-18x

3. Distribute the other term in g(x) to each term in f(x).

   (-3)(5x2+2x-3)= -15x2-6x+9

4. Combine the like terms of both answers.

   30x3+12x2-18x-15x2-6x+9= <em><u>30x3-3x2-24x+9</u></em>
