Question

-2(a4-3a²)-3a(a4+2a)+2a²(a³-2)

Answer 1

Let's simplify step-by-step.

−2(a^4−3a^2)−3a(a^4+2a)+2a^2(a^3−2)

Distribute:

=(−2)(a^4)+(−2)(−3a^2)+−3a^5+−6a^2+(2a^2)(a^3)+(2a^2)(−2)

=−2a^4+6a^2+−3a^5+−6a^2+2a^5+−4a^2

Combine Like Terms:

=−2a^4+6a^2+−3a^5+−6a^2+2a^5+−4a^2

=(−3a^5+2a^5)+(−2a^4)+(6a^2+−6a^2+−4a^2)

=−a^5+−2a^4+−4a^2

Answer:

=−a^5−2a^4−4a^2
