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

expand

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

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

Solution steps

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

Expand

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

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

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

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

(1 - 3 x) (x + 2)^{'}

2 t (2 t - 2)

[(x + 1) (x - 1)] 2
