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

expand

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

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

Solution steps

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

Expand

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

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

\frac{2 s ^{2} - 6 s + 5}{( s - 1 ) ( s - 2 ) ( s - 3 )}

\frac{x + 3}{x ( x + 7 )}

\frac{4 ( n + 1 ) ( 2 n + 1 )}{3 n ^{2}}

(4 k^{5}) 2

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