a.) 3x 3 + 13x 2 - 10x + 5
b.) 3x 3 + 13x 2 - 10x + 6
c.) 3x 3 + 6x 2 - 6x + 6
d.) 3x 3 + 13x 2 - 9x + 5
e.) 3x 3 + 17x 2 - 9x + 5

Thanks for your help ladies and gents

Find the product of
( x + 5) (3x^2 - 2x + 1)
= 3x^3 - 2x^2 + x + 15x^2 - 10x + 5
= 3x^3 + 13x^2 - 9x + 5
Answer choice:
d) 3x 3 + 13x 2 - 9x + 5

You will use the same idea as using FOIL. Multiply both terms in the first polynomial by each term in the second polynomial. Then combine like terms.

( x + 5 ) ( 3x^2 - 2x + 1 )
= 3x^3 - 2x^2 + x + 15x^2 - 10x + x
= combine like terms and you are done.

3X3 +13X2 -9X +5

no correct choose.
