derivative of sqrt(x)(2x+4)

Solution

\frac{d}{d x} (x (2 x + 4))

Solution

\frac{3 x + 2}{x}

Solution steps

\frac{d}{d x} (x (2 x + 4))

Apply the Product Rule:

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

f = x, g = 2 x + 4

= \frac{d}{d x} (x) (2 x + 4) + \frac{d}{d x} (2 x + 4) x

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

\frac{d}{d x} (2 x + 4) = 2

= \frac{1}{2 x} (2 x + 4) + 2 x

Simplify

\frac{1}{2 x} (2 x + 4) + 2 x : \frac{3 x + 2}{x}

= \frac{3 x + 2}{x}
