expand-9/((x+1)^2(x-2))

expand

- \frac{9}{( x + 1 ) ^{2} ( x - 2 )}

- \frac{9}{x ^{3} - 3 x - 2}

Solution steps

- \frac{9}{( x + 1 ) ^{2} ( x - 2 )}

(x + 1)^{2} = x^{2} + 2 x + 1

= - \frac{9}{( x ^{2} + 2 x + 1 ) ( x - 2 )}

Expand

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

= - \frac{9}{x ^{3} - 3 x - 2}

3 (2 - (x) = - 2 ((x - 10) - 3 x))

\frac{k ( s + 2 )}{s ( s + 20 ) ( s - 1 )}

2000 ((ln (3)) - 100 (ln (2)))

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

(r - e)^{3} + (r - e)^{2}
