expand (2pq)/((1-q)^3)

expand

\frac{2 pq}{( 1 - q ) ^{3}}

\frac{2 pq}{1 - 3 q + 3 q ^{2} - q ^{3}}

Solution steps

\frac{2 pq}{( 1 - q ) ^{3}}

(1 - q)^{3} = 1 - 3 q + 3 q^{2} - q^{3}

= \frac{2 pq}{1 - 3 q + 3 q ^{2} - q ^{3}}

\frac{x ^{2} - 3 x + 6}{x ( x - 2 ) ( x - 1 )}

\frac{x ^{4} + 1}{x ^{2}}

(9 - 6 x + x^{2})^{3} \cdot 4

(4 x^{2} + 2 x - 1) (2 x - 1)!

\frac{s + 34}{( s + 5 + 3 j ) ( s + 5 - 3 j )}
