expand (-x^2+3)/((x^2+3)^2)

expand

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

\frac{- x ^{2} + 3}{x ^{4} + 6 x ^{2} + 9}

Solution steps

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

(x^{2} + 3)^{2} = x^{4} + 6 x^{2} + 9

= \frac{- x ^{2} + 3}{x ^{4} + 6 x ^{2} + 9}

x^{x - 1} (ln (x) + \frac{x - 1}{x})

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

\frac{( 0.0224 - 2 x ) ^{2}}{( 0.00623 - x ) ( 0.00414 - x )}

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

(a + 1 - a - 1)^{2}
