$(- 9 x^{2} y^{2} + 5 x^{2} y - 11 x y + 1) + (5 x^{2} y^{2} - 15 x y - 11)$

Step 1

Remove parentheses.

$- 9 x^{2} y^{2} + 5 x^{2} y - 11 x y + 1 + 5 x^{2} y^{2} - 15 x y - 11$

Step 2

Add $- 9 x^{2} y^{2}$ and $5 x^{2} y^{2}$ .

$- 4 x^{2} y^{2} + 5 x^{2} y - 11 x y + 1 - 15 x y - 11$

Step 3

Subtract $15 x y$ from $- 11 x y$ .

$- 4 x^{2} y^{2} + 5 x^{2} y - 26 x y + 1 - 11$

Step 4

Subtract $11$ from $1$ .

$- 4 x^{2} y^{2} + 5 x^{2} y - 26 x y - 10$
