$- \frac{2 x^{2}}{5 y^{2}}$

Step 1

This derivative could not be completed using the quotient rule. Mathway will use another method.

Step 2

Since $- \frac{2}{5 y^{2}}$ is constant with respect to $x$ , the derivative of $- \frac{2 x^{2}}{5 y^{2}}$ with respect to $x$ is $- \frac{2}{5 y^{2}} \frac{d}{d x} [x^{2}]$ .

$- \frac{2}{5 y^{2}} \frac{d}{d x} [x^{2}]$

Step 3

Differentiate using the Power Rule which states that $\frac{d}{d x} [x^{n}]$ is $n x^{n - 1}$ where $n = 2$ .

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

Step 4.3

Multiply $- 2$ by $2$ .

$\frac{- 4}{5 y^{2}} x$

Step 4.4

Combine $\frac{- 4}{5 y^{2}}$ and $x$ .

$\frac{- 4 x}{5 y^{2}}$

Step 4.5

Move the negative in front of the fraction.
