$(- 7 m n + 8 m n^{2} - 8 m^{2} n^{2}) + (10 m^{2} n + 2 m^{2} n^{2} - 3 m n)$

Step 1

Remove parentheses.

$- 7 m n + 8 m n^{2} - 8 m^{2} n^{2} + 10 m^{2} n + 2 m^{2} n^{2} - 3 m n$

Step 2

Subtract $3 m n$ from $- 7 m n$ .

$- 10 m n + 8 m n^{2} - 8 m^{2} n^{2} + 10 m^{2} n + 2 m^{2} n^{2}$

Step 3

Add $- 8 m^{2} n^{2}$ and $2 m^{2} n^{2}$ .

$- 10 m n + 8 m n^{2} - 6 m^{2} n^{2} + 10 m^{2} n$
