Answer 1

Answer:

2·(2a^3 - a^2+6)

Step-by-step explanation:

(((0-(5•(a^3)))-(7•(a^2)))+3)+(((9•(a^3))+5a^2)+9)

(((0-(5•(a^3)))-(7•(a^2)))+3)+((3^2a^3+5a^2)+9)

(((0-(5•(a^3)))-7a^2)+3)+(9a^3+5a^2+9)

(((0 -  5a^3) -  7a^2) +  3) +  (9a^3 + 5a^2 + 9)

  Pull out like factors :

4a3 - 2a2 + 12  =   2 • (2a3 - a2 + 6)

Hope it helps!
