derivative of

(5 - 7 x)^{3}

- 21 (5 - 7 x)^{2}

Solution steps

\frac{d}{d x} ((5 - 7 x)^{3})

Apply the chain rule:

3 (5 - 7 x)^{2} \frac{d}{d x} (5 - 7 x)

= 3 (5 - 7 x)^{2} \frac{d}{d x} (5 - 7 x)

\frac{d}{d x} (5 - 7 x) = - 7

= 3 (5 - 7 x)^{2} (- 7)

Simplify

= - 21 (5 - 7 x)^{2}

12 (x - \frac{1}{x})^{2}, at x = 2

\frac{d}{d x} (\frac{1 - x ^{2}}{1 + x ^{2}})

\frac{d y}{d x} = - 4 y

x^{4} - 8 x^{2} + 16

x^{2} + 2 x
