expand-(8e^x)/((e^x+2)^2)+1

expand

- \frac{8 e ^{x}}{( e ^{x} + 2 ) ^{2}} + 1

- \frac{8 e ^{x}}{e ^{2 x} + 4 e ^{x} + 4} + 1

Solution steps

- \frac{8 e ^{x}}{( e ^{x} + 2 ) ^{2}} + 1

(e^{x} + 2)^{2} = e^{2 x} + 4 e^{x} + 4

= - \frac{8 e ^{x}}{4 e ^{x} + e ^{2 x} + 4} + 1

(z - 1 - i)^{2}

(sin (t^{3}) - 5 cos (t^{4}) + t^{4}) \cdot (3 t^{2} - 4 t^{3})

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

cos (x) (3 y cos (x) - x y sin (x))

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