derivative of (x^2)/(x+8)

Solution

derivative of

\frac{x ^{2}}{x + 8}

Solution

\frac{x ^{2} + 16 x}{( x + 8 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{x ^{2}}{x + 8})

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= \frac{\frac{d}{d x} ( x ^{2} ) ( x + 8 ) - \frac{d}{d x} ( x + 8 ) x ^{2}}{( x + 8 ) ^{2}}

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

\frac{d}{d x} (x + 8) = 1

= \frac{2 x ( x + 8 ) - 1 \cdot x ^{2}}{( x + 8 ) ^{2}}

Simplify

\frac{2 x ( x + 8 ) - 1 \cdot x ^{2}}{( x + 8 ) ^{2}} : \frac{x ^{2} + 16 x}{( x + 8 ) ^{2}}

= \frac{x ^{2} + 16 x}{( x + 8 ) ^{2}}
