derivative of sqrt(x)(sqrt(x)+1)

Solution

\frac{d}{d x} (x (x + 1))

Solution

\frac{x + 1}{2 x} + \frac{1}{2}

Solution steps

\frac{d}{d x} (x (x + 1))

Apply the Product Rule:

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

f = x, g = x + 1

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

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

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

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

Simplify

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

= \frac{x + 1}{2 x} + \frac{1}{2}
