\frac{d}{d x} (x (4 - x))

4 - 2 x

Solution steps

\frac{d}{d x} (x (4 - x))

Apply the Product Rule:

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

f = x, g = 4 - x

= \frac{d x}{d x} (4 - x) + \frac{d}{d x} (4 - x) x

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

\frac{d}{d x} (4 - x) = - 1

= 1 \cdot (4 - x) + (- 1) x

Simplify

1 \cdot (4 - x) + (- 1) x : 4 - 2 x

= 4 - 2 x
