expand (10z)/((z-1)(z+2))

expand

\frac{10 z}{( z - 1 ) ( z + 2 )}

\frac{10 z}{z ^{2} + z - 2}

Solution steps

\frac{10 z}{( z - 1 ) ( z + 2 )}

Expand

(z - 1) (z + 2) : z^{2} + z - 2

= \frac{10 z}{z ^{2} + z - 2}

\frac{100 ( x + 55 )}{x + 550}

\frac{n ^{2}}{( 2 i d x + 2 i ^{2} d ^{2} ) ( s + x + i d )}

(- 3 + Δ x)^{3}

(C x + C e^{- x}) x

\frac{\partial}{\partial y} ((x) (x^{3} y z^{2} + 2 yz))
