Question

Simplify (3a^3-7a^2+a)-(6a^3-4a^2-8).

Answer 1

Hey! I think your answer will be -12a^2+a+8

Answer 2

Answer: −3a^3−3a^2+a+8

Step-by-step explanation:  (3a^3-7a^2+a)-(6a^3-4a^2-8)

3a^3+−7a^2+a+−1(6a^3)+−1(−4a^2)+(−1)(−8)

3a^3+−7a^2+a+−6a^3+4a^2+8

(3a^3+−6a^3)+(−7a^2+4a^2)+(a)+(8)

−3a^3+−3a^2+a+8
