Your answer should be a polynomial in standard form.
(8 - 3a)(2a2 + 6) =

Answer 1

-6a^3 + 16a^2 - 18a + 48.

Explanation:

(8 - 3a)(2a2 + 6) =

= 8*2a^2 + 8*6 - 3a*2a^2 - 3a*6

= -6a^3 + 16a^2 - 18a + 48.

Answer 2

`(8-3a)(2a^2+6)=8\cdot2a^2+8\cdot6-3a\cdot2a^2-3a\cdot6=\\\\=16a^2+48-6a^3-18a=\boxed{-6a^3+16a^2-18a+48}`
