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

expand

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

\frac{x + y}{x ^{2} - 3 x + 2}

Solution steps

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

Expand

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

= \frac{x + y}{x ^{2} - 3 x + 2}

sin^{3} (x) cos (x) (sin^{3} (x) + cos (2 x))

- \frac{1}{2} s (s + 1) (s + 5) (s + 10)

(1 + sin (a)) (1 - sin (a)) - cos^{2} (a)

(9 cos (t) sin (t) + 9 cos^{2} (t))^{2}
