Answer 1

Answer:

-14 a^2 -13a -5

Step-by-step explanation:

[ (3a^3 +a^2-7) + (6a^3 -2a^2-3a+2)] - [ ( 2a^3 -5a^2+8a) + (7a^3 -8a^2+2a+10)]

= [ (3a^3 + 6a3) +(a^2- 2a^2)+(-7+2)] - [ (-2a^3) +(-5a^2 -8a^2) + (8a +2a) +(10)]

= [ 9a^3-a^2 +3a-5] - [ -9a^3-13a^2+10a+10]

= (9a^3- 9a^3) -(-a^2 - 13a^2) - (3a + 10a) -(-5+10)

= -14a^ 2 -13a-5
