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

expand

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

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

Solution steps

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

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

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

(x + 1) (x - x + 1)

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

(- 23 - 2 i)^{5}

(x - x^{2}) (sin (x) + x^{2} - 15)

(x - 5 - 2) (3 + x)
