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

expand

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

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

Solution steps

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

(x^{2} + x - 2)^{2} = x^{4} + 2 x^{3} - 3 x^{2} - 4 x + 4

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

(20 b d z + 32 c g a) + k (20 b d z + 32 c g a)

(\frac{b}{a} (x - z) + y - c)^{2}

2 (e - 1) + \frac{e ^{6} + e ^{2} - 2}{4 e ^{2}}

\frac{1}{t ^{2}} (1 + e^{2 t} - 2 e^{t})

\frac{s}{( s + 4 ) ( s + 8 )}
