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

Step 1

Remove parentheses.

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

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 $- 9 y$ .

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

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
