$(- 8 y^{2} - 9 y) + (8 y^{3} + 9 y^{2} - 2 y)$

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 $- 8 y^{2}$ and $9 y^{2}$ .

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

Step 3

Subtract $2 y$ from $- 9 y$ .

$y^{2} + 8 y^{3} - 11 y$

Step 4

Reorder $y^{2}$ and $8 y^{3}$ .

$8 y^{3} + y^{2} - 11 y$
