\frac{d}{d x} (r (x) x)

x \frac{d}{d x} (r (x)) + r (x)

Solution steps

\frac{d}{d x} (r (x) x)

Apply the Product Rule:

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

f = r (x), g = x

= \frac{d}{d x} (r (x)) x + \frac{d x}{d x} r (x)

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

= \frac{d}{d x} (r (x)) x + 1 \cdot r (x)

Simplify

= x \frac{d}{d x} (r (x)) + r (x)
