expand (18x)/((9-x^2)^2)

expand

\frac{18 x}{( 9 - x ^{2} ) ^{2}}

\frac{18 x}{81 - 18 x ^{2} + x ^{4}}

Solution steps

\frac{18 x}{( 9 - x ^{2} ) ^{2}}

(9 - x^{2})^{2} = 81 - 18 x^{2} + x^{4}

= \frac{18 x}{81 - 18 x ^{2} + x ^{4}}

\frac{( sin ( a ) + tan ( a ) ) cot ( a )}{csc ( a ) + cot ( a )}
