expand ((x-1)(x+5))/((x-4)(x+2))

expand

\frac{( x - 1 ) ( x + 5 )}{( x - 4 ) ( x + 2 )}

\frac{x ^{2} + 4 x - 5}{x ^{2} - 2 x - 8}

Solution steps

\frac{( x - 1 ) ( x + 5 )}{( x - 4 ) ( x + 2 )}

Expand

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

= \frac{( x - 1 ) ( x + 5 )}{x ^{2} - 2 x - 8}

Expand

(x - 1) (x + 5) : x^{2} + 4 x - 5

= \frac{x ^{2} + 4 x - 5}{x ^{2} - 2 x - 8}

\frac{( s ^{3} + 11 s ^{2} - s + 1 )}{s ( s - 1 ) ( s ^{2} - 36 )}

5 (cos (x) + 3)

x^{\frac{2}{5}} (x - 7)

\frac{2 x - 3}{4 ( 2 x + 80 )}

(2 + 5) (1 - 5)
