\frac{d}{d x} ((1 + 5 x^{2}) (x - x^{2}))

- 20 x^{3} + 15 x^{2} - 2 x + 1

Solution steps

\frac{d}{d x} ((1 + 5 x^{2}) (x - x^{2}))

Apply the Product Rule:

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

f = 1 + 5 x^{2}, g = x - x^{2}

= \frac{d}{d x} (1 + 5 x^{2}) (x - x^{2}) + \frac{d}{d x} (x - x^{2}) (1 + 5 x^{2})

\frac{d}{d x} (1 + 5 x^{2}) = 10 x

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

= 10 x (x - x^{2}) + (1 - 2 x) (1 + 5 x^{2})

Simplify

10 x (x - x^{2}) + (1 - 2 x) (1 + 5 x^{2}) : - 20 x^{3} + 15 x^{2} - 2 x + 1

= - 20 x^{3} + 15 x^{2} - 2 x + 1

x \to 0 lim (\frac{2}{x ^{2} ( x + 7 )})

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

\frac{d}{d x} (8 x - x^{2})

\int 6 cos (6 x) - 5 d x

\frac{\partial}{\partial x} (x - 1)
