\frac{d}{d x} (\frac{x ^{2} + 1}{x - 2})

\frac{x ^{2} - 4 x - 1}{( x - 2 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{x ^{2} + 1}{x - 2})

Apply the Quotient Rule:

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

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

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

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

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

Simplify

\frac{2 x ( x - 2 ) - 1 \cdot ( x ^{2} + 1 )}{( x - 2 ) ^{2}} : \frac{x ^{2} - 4 x - 1}{( x - 2 ) ^{2}}

= \frac{x ^{2} - 4 x - 1}{( x - 2 ) ^{2}}

\int_{- 2}^{- 1} \frac{1}{x} d x

\int_{- 1}^{1} x^{2} + 1 d x

f (x) = x^{2} - 2, at x = a

\int x^{2} sin (2 x) x d x

\int \frac{x + 1}{x ^{2} + 7 x + 10} d x
