expand (-x^2+6x-4)/((x^2-4)^2)

expand

\frac{- x ^{2} + 6 x - 4}{( x ^{2} - 4 ) ^{2}}

\frac{- x ^{2} + 6 x - 4}{x ^{4} - 8 x ^{2} + 16}

Solution steps

\frac{- x ^{2} + 6 x - 4}{( x ^{2} - 4 ) ^{2}}

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

= \frac{- x ^{2} + 6 x - 4}{x ^{4} - 8 x ^{2} + 16}

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

(x y^{2} + x) d x

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

(2 + 6 e^{- 2 x})^{2}

\frac{( 1 + 6 x ) ^{5}}{5}
