$y' = \frac{4 x (- (x^{6} + 3 x^{4} y + 3 x^{2} y^{2}) - (y^{3}))}{2 x^{6} + 6 x^{4} y + 6 x^{2} y^{2} + 2 y^{3} - 1}$

Step 5.5.3.5.7

Factor $- 1$ out of $- (x^{6} + 3 x^{4} y + 3 x^{2} y^{2}) - (y^{3})$ .

$y' = \frac{4 x (- (x^{6} + 3 x^{4} y + 3 x^{2} y^{2} + y^{3}))}{2 x^{6} + 6 x^{4} y + 6 x^{2} y^{2} + 2 y^{3} - 1}$

Step 5.5.3.5.8.1

Rewrite $- (x^{6} + 3 x^{4} y + 3 x^{2} y^{2} + y^{3})$ as $- 1 (x^{6} + 3 x^{4} y + 3 x^{2} y^{2} + y^{3})$ .

$y' = \frac{4 x (- 1 (x^{6} + 3 x^{4} y + 3 x^{2} y^{2} + y^{3}))}{2 x^{6} + 6 x^{4} y + 6 x^{2} y^{2} + 2 y^{3} - 1}$

Step 5.5.3.5.8.2

Move the negative in front of the fraction.

$y' = - \frac{(4 x) (x^{6} + 3 x^{4} y + 3 x^{2} y^{2} + y^{3})}{2 x^{6} + 6 x^{4} y + 6 x^{2} y^{2} + 2 y^{3} - 1}$

Step 5.5.3.5.8.3

Reorder factors in $- \frac{(4 x) (x^{6} + 3 x^{4} y + 3 x^{2} y^{2} + y^{3})}{2 x^{6} + 6 x^{4} y + 6 x^{2} y^{2} + 2 y^{3} - 1}$ .

$y' = - \frac{4 x (x^{6} + 3 x^{4} y + 3 x^{2} y^{2} + y^{3})}{2 x^{6} + 6 x^{4} y + 6 x^{2} y^{2} + 2 y^{3} - 1}$

Step 6

Replace $y'$ with $\frac{d y}{d x}$ .

$\frac{d y}{d x} = - \frac{4 x (x^{6} + 3 x^{4} y + 3 x^{2} y^{2} + y^{3})}{2 x^{6} + 6 x^{4} y + 6 x^{2} y^{2} + 2 y^{3} - 1}$
