derivative of

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

2 x - 21 x^{2}

Solution steps

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

Apply the Product Rule:

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

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

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

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

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

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

Simplify

2 x (1 - 7 x) + (- 7) x^{2} : 2 x - 21 x^{2}

= 2 x - 21 x^{2}
