$- \frac{- 1 (12 x^{4} y^{4} + 3 x^{2} y - 8 x^{4} + 72 y^{2})}{36 x y^{2}}$

Step 15.2

Move the negative in front of the fraction.

$- - \frac{12 x^{4} y^{4} + 3 x^{2} y - 8 x^{4} + 72 y^{2}}{36 x y^{2}}$

Step 15.3

Multiply $- 1$ by $- 1$ .

$1 \frac{12 x^{4} y^{4} + 3 x^{2} y - 8 x^{4} + 72 y^{2}}{36 x y^{2}}$

Step 15.4

Multiply $\frac{12 x^{4} y^{4} + 3 x^{2} y - 8 x^{4} + 72 y^{2}}{36 x y^{2}}$ by $1$ .

$\frac{12 x^{4} y^{4} + 3 x^{2} y - 8 x^{4} + 72 y^{2}}{36 x y^{2}}$
