Simplify -3mn+m^2n+3mn-mn^2+2m-m

$- 3 m n + m^{2} n + 3 m n - m n^{2} + 2 m - m$

Step 1

Combine the opposite terms in $- 3 m n + m^{2} n + 3 m n - m n^{2} + 2 m - m$ .

Add $- 3 m n$ and $3 m n$ .

$m^{2} n + 0 - m n^{2} + 2 m - m$

Add $m^{2} n$ and $0$ .

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

Step 2

Subtract $m$ from $2 m$ .

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