expand (x^3)/((7+14x^2)^2)

expand

\frac{x ^{3}}{( 7 + 14 x ^{2} ) ^{2}}

\frac{x ^{3}}{49 + 196 x ^{2} + 196 x ^{4}}

Solution steps

\frac{x ^{3}}{( 7 + 14 x ^{2} ) ^{2}}

(7 + 14 x^{2})^{2} = 49 + 196 x^{2} + 196 x^{4}

= \frac{x ^{3}}{49 + 196 x ^{2} + 196 x ^{4}}

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

(x - \frac{π}{4})^{2}

cos (u) (t - π)

e^{3 (l n (x) + 3)}

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