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

expand

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

\frac{x ^{2} - x - 2}{x ^{2} - 2 x - 8}

Solution steps

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

Expand

(x + 2) (x - 4) : x^{2} - 2 x - 8

= \frac{( x + 1 ) ( x - 2 )}{x ^{2} - 2 x - 8}

Expand

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

= \frac{x ^{2} - x - 2}{x ^{2} - 2 x - 8}

\frac{( x - 1 ) ( x + 2 )}{( x - 3 ) ( x + 7 )}

- \frac{12 s ^{2} - 35 s + 28}{2 ( s + 1 ) ^{2} ( s - 2 )}

5 (2 + 9)

\frac{48 x ^{2} + 3 x + 18}{( 5 x ^{2} + x + 3 ) ( x - 3 )}

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