derivative of

(1 - x) (x^{2} - 7)^{2}

- 5 x^{4} + 4 x^{3} + 42 x^{2} - 28 x - 49

Solution steps

\frac{d}{d x} ((1 - x) (x^{2} - 7)^{2})

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = 1 - x, g = (x^{2} - 7)^{2}

= \frac{d}{d x} (1 - x) (x^{2} - 7)^{2} + \frac{d}{d x} ((x^{2} - 7)^{2}) (1 - x)

\frac{d}{d x} (1 - x) = - 1

\frac{d}{d x} ((x^{2} - 7)^{2}) = 4 x (x^{2} - 7)

= (- 1) (x^{2} - 7)^{2} + 4 x (x^{2} - 7) (1 - x)

Simplify

(- 1) (x^{2} - 7)^{2} + 4 x (x^{2} - 7) (1 - x) : - 5 x^{4} + 4 x^{3} + 42 x^{2} - 28 x - 49

= - 5 x^{4} + 4 x^{3} + 42 x^{2} - 28 x - 49

y = \frac{9}{x ^{2} + 5}, (2, 1)

\frac{\partial}{\partial x} (6 x^{2} + 11 y)

e^{- 14 x}

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