\frac{d}{d x} (\frac{x ^{2} - 3}{x + 2})

\frac{x ^{2} + 4 x + 3}{( x + 2 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{x ^{2} - 3}{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} - 3 ) ( x + 2 ) - \frac{d}{d x} ( x + 2 ) ( x ^{2} - 3 )}{( x + 2 ) ^{2}}

\frac{d}{d x} (x^{2} - 3) = 2 x

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

= \frac{2 x ( x + 2 ) - 1 \cdot ( x ^{2} - 3 )}{( x + 2 ) ^{2}}

Simplify

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

= \frac{x ^{2} + 4 x + 3}{( x + 2 ) ^{2}}

\int_{0}^{4} 4 x d x

\int \frac{sin ( x )}{( 1 + cos ( x ) ) ^{3}} d x

x^{^{''}} = 0

\int cos^{5} (x) sin (x) d x

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