derivative of f(x)=x(2-x)^2

Solution

derivative of

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

Solution

3 x^{2} - 8 x + 4

Solution steps

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

Apply the Product Rule:

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

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

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

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

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

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

Simplify

1 \cdot (2 - x)^{2} + (- 2 (2 - x)) x : 3 x^{2} - 8 x + 4

= 3 x^{2} - 8 x + 4
