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

expand

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

\frac{x + 5}{x ^{3} - x + 4 x ^{2} - 4}

Solution steps

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

Expand

(x + 4) (x^{2} - 1) : x^{3} - x + 4 x^{2} - 4

= \frac{x + 5}{x ^{3} - x + 4 x ^{2} - 4}

(12 + tan (x)) (12 - tan (x)) + sec^{2} (x)

(2 x + 5) (7 x - 6)

(1 + 5)^{2}

(2 sin (x) - cos (x))^{2}

11 (11 + x 33)
