Answer:

− 3 a ^3 + 5 a ^2 − 3 a + 7

Explanation:

Apply the distributive property.

a ^3 − 2 a + 5 − ( 4 a ^3 ) − ( − 5 a ^2 ) − a − − 2

Simplify.

a ^3 − 2 a + 5 − 4 a ^3 + 5 a ^2 − a + 2

Simplify by adding terms.

Subtract 4 a ^3 from a ^3 .

− 3 a ^3 − 2 a + 5 + 5 a ^2 − a + 2

Subtract a from − 2 a .

− 3 a ^3 − 3 a + 5 + 5 a ^2 + 2

Simplify the expression.

Add 5 and 2 .

− 3 a^ 3 − 3 a + 5 a ^2 + 7

Move − 3 a .

− 3 a ^3 + 5 a ^2 − 3 a + 7

I hope this helped. I am sorry if you get this wrong.
