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

expand

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

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

Solution steps

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

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

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

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

2 (1 + 6)

(23 - 2 i)^{5}

(- 1 - 2 i)^{2}

f (x, y) (x^{2} - 3 x y + x - y^{2} + 4) - λ (x + y - 2)
