Question

Simplifique (1-a)³+2a(-2a²)+(1-a³)

Answer 1

Answer:

−6a3+3a2−3a+2

Step-by-step explanation:

Let's simplify step-by-step.

(1−a)3+2a(−2a2)+1−a3

Distribute:

=−a3+3a2+−3a+1+2a(−2a2)+1+−a3

=−a3+3a2+−3a+1+−4a3+1+−a3

Combine Like Terms:

=−a3+3a2+−3a+1+−4a3+1+−a3

=(−a3+−4a3+−a3)+(3a2)+(−3a)+(1+1)

=−6a3+3a2+−3a+2

Answer:

=−6a3+3a2−3a+2
