expand (2x)/((x-2)(x+1))

expand

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

\frac{2 x}{x ^{2} - x - 2}

Solution steps

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

Expand

(x - 2) (x + 1) : x^{2} - x - 2

= \frac{2 x}{x ^{2} - x - 2}

(A + B = 1,) - (- 2 A + B = - 1)

\frac{6}{x} + \frac{9}{2} x

\frac{1}{z ^{2} ( z - 2 ) ^{2}}

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

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