$(- 5 a^{3} - 2 a^{2}) + (6 a^{3} + 9 a^{2} + 8 a)$

Step 1

To write a polynomial in standard form, simplify and then arrange the terms in descending order.

$a x^{2} + b x + c$

Step 2

Add $- 5 a^{3}$ and $6 a^{3}$ .

$a^{3} - 2 a^{2} + 9 a^{2} + 8 a$

Step 3

Add $- 2 a^{2}$ and $9 a^{2}$ .

$a^{3} + 7 a^{2} + 8 a$
