(d^2)/(dx^2)((x^2)/(1+x))

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

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

Solution steps

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

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

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

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

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

\frac{5 x}{x + 2}

7 x^{3}

\frac{\partial}{\partial x} (cos (x) + sin (y))

\int x^{6} ln (2 x) d x

\frac{d y}{d t} = 3 y + y^{6}
