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

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

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

Solution steps

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

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

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

\frac{d}{d x} (- \frac{4 x}{( x ^{2} - 1 ) ^{2}}) = - \frac{4 ( - 3 x ^{2} - 1 )}{( x ^{2} - 1 ) ^{3}}

= - \frac{4 ( - 3 x ^{2} - 1 )}{( x ^{2} - 1 ) ^{3}}

x^{4} + 2 x

\int_{4}^{6} x^{3} d x

y = (k (x)^{2} + x^{2})^{4} (x + k (x))

\frac{\partial}{\partial x} (x^{2} y + y ln (x z^{3}))

\int 3 x^{4} + \frac{7}{4} x^{5} d x
