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

expand

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

\frac{4 + x ^{2}}{16 - 8 x ^{2} + x ^{4}}

Solution steps

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

(4 - x^{2})^{2} = 16 - 8 x^{2} + x^{4}

= \frac{4 + x ^{2}}{16 - 8 x ^{2} + x ^{4}}

\frac{1}{( 2 n + 1 ) ( 2 n - 1 )}

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

(2 - a)^{10}

π (4 y)^{2} - π (y^{2})^{2}

\frac{3 x - 7}{( x - 1 ) ( x + 1 ) ^{2}}
