expand (21)/((x+7)^2)

expand

\frac{21}{( x + 7 ) ^{2}}

\frac{21}{x ^{2} + 14 x + 49}

Solution steps

\frac{21}{( x + 7 ) ^{2}}

(x + 7)^{2} = x^{2} + 14 x + 49

= \frac{21}{x ^{2} + 14 x + 49}

4 - \frac{8 e ^{0.13 x}}{( 1 + e ^{0.13 x} ) ^{2}}

\frac{d}{d t} ((k) (s k^{α} - nk))

e^{2 (x + i y)}

(x^{2} + 2 x - 1)^{3} (5 x)

(y e^{- x} - sin (x)) d x - (e^{- x} + 2 y) d y
