Question
Simplify:
$ a^2(2 a-1)+3 a+a^3-8 $
$ a^2(2 a-1)+3 a+a^3-8 $
✓
Answer
To simplify, we will use distributive law as follows:
$ a^2(2 a-1)+3 a+a^3-8 $
$ =2 a^3-a^2+3 a+a^3-8 $
$ =2 a^3+a^3-a^2+3 a-8 $
$ =3 a^3-a^2+3 a-8 $
$ a^2(2 a-1)+3 a+a^3-8 $
$ =2 a^3-a^2+3 a+a^3-8 $
$ =2 a^3+a^3-a^2+3 a-8 $
$ =3 a^3-a^2+3 a-8 $
