$\frac{- 3 y^{2} (- 10 x^{2})}{5 x (y)}$

Step 3

Cancel the common factor of $y^{2}$ and $y$ .

Factor $y$ out of $- 3 y^{2} (- 10 x^{2})$ .

$\frac{y (- 3 y (- 10 x^{2}))}{5 x (y)}$

Cancel the common factors.

Factor $y$ out of $5 x (y)$ .

$\frac{y (- 3 y (- 10 x^{2}))}{y (5 x)}$

Cancel the common factor.

$\frac{y (- 3 y (- 10 x^{2}))}{y (5 x)}$

Rewrite the expression.

$\frac{- 3 y (- 10 x^{2})}{5 x}$

$\frac{- 3 y (- 10 x^{2})}{5 x}$

$\frac{- 3 y (- 10 x^{2})}{5 x}$

Step 4

Cancel the common factor of $- 10$ and $5$ .

Factor $5$ out of $- 3 y (- 10 x^{2})$ .

$\frac{5 (- 3 y (- 2 x^{2}))}{5 x}$

Cancel the common factors.

Factor $5$ out of $5 x$ .
