(d^2)/(dx^2)((x^2+2x-6)/((x+1)^2))

\frac{d ^{2}}{d x ^{2}} (\frac{x ^{2} + 2 x - 6}{( x + 1 ) ^{2}})

- \frac{42}{( x + 1 ) ^{4}}

Solution steps

\frac{d ^{2}}{d x ^{2}} (\frac{x ^{2} + 2 x - 6}{( x + 1 ) ^{2}})

\frac{d}{d x} (\frac{x ^{2} + 2 x - 6}{( x + 1 ) ^{2}}) = \frac{14}{( x + 1 ) ^{3}}

= \frac{d}{d x} (\frac{14}{( x + 1 ) ^{3}})

\frac{d}{d x} (\frac{14}{( x + 1 ) ^{3}}) = - \frac{42}{( x + 1 ) ^{4}}

= - \frac{42}{( x + 1 ) ^{4}}

\int_{0}^{\frac{π}{24}} tan (8 x) d x

e^{1 + x^{2}} + 3 x^{4}

\frac{d y}{d x} y = sin (- 1 (6 x + 1))

\int 10 x 3 x^{2} - 4 d x

\frac{\partial}{\partial y} (x^{2} + 2 y^{2} - x^{2} y)
