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

expand

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

\frac{9 x}{x ^{3} + 3 x ^{2} - 4}

Solution steps

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

(x + 2)^{2} = x^{2} + 4 x + 4

= \frac{9 x}{( x - 1 ) ( x ^{2} + 4 x + 4 )}

Expand

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

= \frac{9 x}{x ^{3} + 3 x ^{2} - 4}

- \frac{( - 1 ) ^{n} - 1}{π ^{2} n ^{2}}

(4 y e^{4 x y} - \frac{3}{y}) d x

x^{2} d v (v - v x^{2} d v)

\frac{2 ( 5 - 10 )}{3}

e^{\frac{25 l n ( 63 ) - 6 ( 5 l n ( 3 ) + 6 l n ( 7 ) )}{28}}
