expand (x^2e^x)/((e^x+1)^2)

expand

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

\frac{e ^{x} x ^{2}}{e ^{2 x} + 2 e ^{x} + 1}

Solution steps

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

(e^{x} + 1)^{2} = e^{2 x} + 2 e^{x} + 1

= \frac{e ^{x} x ^{2}}{e ^{2 x} + 2 e ^{x} + 1}

\frac{\partial}{\partial x} ((y) (y - x))

\frac{\partial}{\partial a} ((x) (a x^{5} + b x + 3))

A (6, - 8) B (4, 2)

(e^{2 x} + 1)^{3}

\frac{5 x - 1}{( x + 1 ) ( x - 2 )}
