expand (az)/((1-bz)^2)

expand

\frac{a z}{( 1 - b z ) ^{2}}

\frac{a z}{1 - 2 z b + z ^{2} b ^{2}}

Solution steps

\frac{a z}{( 1 - b z ) ^{2}}

(1 - b z)^{2} = 1 - 2 z b + z^{2} b^{2}

= \frac{a z}{1 - 2 z b + z ^{2} b ^{2}}

1 - (\frac{1}{2})^{θ} (1 + θ ln (2))

\frac{( a + b ) ^{2}}{a + b - 2}

x (\frac{p - x}{2})

, - x ((b + 1) (2 b + 1)) x - 2 b (b + 1)

\frac{3 ( x - 2 )}{4 ( x + 5 )}
