expand (-4x^2-10x-4)/((x^2-1)^2)

expand

\frac{- 4 x ^{2} - 10 x - 4}{( x ^{2} - 1 ) ^{2}}

\frac{- 4 x ^{2} - 10 x - 4}{x ^{4} - 2 x ^{2} + 1}

Solution steps

\frac{- 4 x ^{2} - 10 x - 4}{( x ^{2} - 1 ) ^{2}}

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

= \frac{- 4 x ^{2} - 10 x - 4}{x ^{4} - 2 x ^{2} + 1}

(- 2, 2) y (3, - 5)

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

(e^{x} + ln (y) + \frac{y}{x}) d x + (\frac{x}{y} + ln (x) + sin (x)) d y

\frac{e ^{s}}{s ( 1 - e ^{- s} )}

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