$(7 m^{2} n - 18 m n^{2}) + (9 m^{2} n - 5 m n^{2} + m n)$

Step 1

Remove parentheses.

$7 m^{2} n - 18 m n^{2} + 9 m^{2} n - 5 m n^{2} + m n$

Step 2

Add $7 m^{2} n$ and $9 m^{2} n$ .

$16 m^{2} n - 18 m n^{2} - 5 m n^{2} + m n$

Step 3

Subtract $5 m n^{2}$ from $- 18 m n^{2}$ .

$16 m^{2} n - 23 m n^{2} + m n$
