expand (x-2)/((x+9)(x-5))

expand

\frac{x - 2}{( x + 9 ) ( x - 5 )}

\frac{x - 2}{x ^{2} + 4 x - 45}

Solution steps

\frac{x - 2}{( x + 9 ) ( x - 5 )}

Expand

(x + 9) (x - 5) : x^{2} + 4 x - 45

= \frac{x - 2}{x ^{2} + 4 x - 45}

- \frac{5}{4} x^{2} + 120 x - \frac{940}{3}

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

5^{2} 3^{2}

\frac{a - 3}{3 ( a - 4 )}

(1 - cos (x)) \cdot sin (x)
