\frac{d}{d x} (x (1 - 2 x)^{3})

(1 - 2 x)^{3} - 6 x (1 - 2 x)^{2}

Solution steps

\frac{d}{d x} (x (1 - 2 x)^{3})

Apply the Product Rule:

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

f = x, g = (1 - 2 x)^{3}

= \frac{d x}{d x} (1 - 2 x)^{3} + \frac{d}{d x} ((1 - 2 x)^{3}) x

\frac{d x}{d x} = 1

\frac{d}{d x} ((1 - 2 x)^{3}) = - 6 (1 - 2 x)^{2}

= 1 \cdot (1 - 2 x)^{3} + (- 6 (1 - 2 x)^{2}) x

Simplify

= (1 - 2 x)^{3} - 6 x (1 - 2 x)^{2}

f (x) = 8 x - 3 x^{2}

\int_{- 1}^{2} \frac{1}{x ^{5}} d x

- \frac{4}{x ^{3}}

\int 2 (x + y) d x

\frac{d ^{2}}{d x ^{2}} (x sin (x))
