Factor 4m^2n^2-4mn^3

$4 m^{2} n^{2} - 4 m n^{3}$

Step 1

Factor $4 m n^{2}$ out of $4 m^{2} n^{2} - 4 m n^{3}$ .

Factor $4 m n^{2}$ out of $4 m^{2} n^{2}$ .

$4 m n^{2} (m) - 4 m n^{3}$

Factor $4 m n^{2}$ out of $- 4 m n^{3}$ .

$4 m n^{2} (m) + 4 m n^{2} (- 1 n)$

Factor $4 m n^{2}$ out of $4 m n^{2} (m) + 4 m n^{2} (- 1 n)$ .

$4 m n^{2} (m - 1 n)$

Step 2

Rewrite $- 1 n$ as $- n$ .

$4 m n^{2} (m - n)$
