Answer 2

Answer:

hi ! here is your answer : 2a^2 - a^3 - a^4

Step-by-step explanation:

a^2 [a^2+1] -a^3 [a+1] -a[a^3 -a]

= a^4 + a^2 - a^4 - a^3 - a^4 + a^2

= a^4 - a^4 -a^4 - a^3 + a^2 + a^2 ( by Rearranging )

= -a^4 - a^3 + a^2 + a^2

=  -a^4 - a^3 + 2a^2

or 2a^2 - a^3 - a^4  ( by rearranging )
