Step 1.1

Add $10 m n$ and $m n$ .

$2 m n - 5 m n^{2} + 8 m^{2} n - (11 m n + 6 m^{2} n - 3 m n^{2})$

Step 1.2

Apply the distributive property.

$2 m n - 5 m n^{2} + 8 m^{2} n - (11 m n) - (6 m^{2} n) - (- 3 m n^{2})$

Step 1.3

Simplify.

Step 1.3.1

Multiply $11$ by $- 1$ .

$2 m n - 5 m n^{2} + 8 m^{2} n - 11 (m n) - (6 m^{2} n) - (- 3 m n^{2})$

Step 1.3.2

Multiply $6$ by $- 1$ .

$2 m n - 5 m n^{2} + 8 m^{2} n - 11 (m n) - 6 (m^{2} n) - (- 3 m n^{2})$

Step 1.3.3

Multiply $- 3$ by $- 1$ .

$2 m n - 5 m n^{2} + 8 m^{2} n - 11 (m n) - 6 (m^{2} n) + 3 (m n^{2})$

Step 1.4

Remove parentheses.

$2 m n - 5 m n^{2} + 8 m^{2} n - 11 m n - 6 m^{2} n + 3 m n^{2}$

Step 2.1

Subtract $11 m n$ from $2 m n$ .

$- 9 m n - 5 m n^{2} + 8 m^{2} n - 6 m^{2} n + 3 m n^{2}$

Step 2.2

Add $- 5 m n^{2}$ and $3 m n^{2}$ .

$- 9 m n - 2 m n^{2} + 8 m^{2} n - 6 m^{2} n$

Step 2.3

Subtract $6 m^{2} n$ from $8 m^{2} n$ .

$- 9 m n - 2 m n^{2} + 2 m^{2} n$
