expand (4x^2)/((1-x^2)^2)

expand

\frac{4 x ^{2}}{( 1 - x ^{2} ) ^{2}}

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

Solution steps

\frac{4 x ^{2}}{( 1 - x ^{2} ) ^{2}}

(1 - x^{2})^{2} = 1 - 2 x^{2} + x^{4}

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

\frac{( ( L + d - x ) ^{2} - x )}{( ( ( L + d - x ) ^{2} - x ) ^{2} + h ^{2} )}

\frac{1}{( s + 1 ) ^{2} \cdot ( s - 2 )}

\frac{6 ( x + 2 )}{( x + 1 ) ( x + 3 ) ( x + 4 )}

\frac{s ^{2} + 2 s - k}{( s ^{2} + k ) ( s - k )}

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