expand (-x^2+25)/((x^2+25)^2)

expand

\frac{- x ^{2} + 25}{( x ^{2} + 25 ) ^{2}}

\frac{- x ^{2} + 25}{x ^{4} + 50 x ^{2} + 625}

Solution steps

\frac{- x ^{2} + 25}{( x ^{2} + 25 ) ^{2}}

(x^{2} + 25)^{2} = x^{4} + 50 x^{2} + 625

= \frac{- x ^{2} + 25}{x ^{4} + 50 x ^{2} + 625}

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

\frac{( x + h ) ^{n} - x ^{n}}{h}

a (1 + cos (θ))

\frac{- x ^{2} - 2 x + 13}{( x - 2 ) ^{2}}

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