derivative of xsqrt(14-x)

Solution

\frac{d}{d x} (x 14 - x)

Solution

\frac{- 3 x + 28}{2 14 - x}

Solution steps

\frac{d}{d x} (x 14 - x)

Apply the Product Rule:

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

f = x, g = 14 - x

= \frac{d x}{d x} 14 - x + \frac{d}{d x} (14 - x) x

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

\frac{d}{d x} (14 - x) = - \frac{1}{2 14 - x}

= 1 \cdot 14 - x + (- \frac{1}{2 14 - x}) x

Simplify

1 \cdot 14 - x + (- \frac{1}{2 14 - x}) x : \frac{- 3 x + 28}{2 14 - x}

= \frac{- 3 x + 28}{2 14 - x}
