expand (z^2-6z+8)/((z+1)(z+2))

expand

\frac{z ^{2} - 6 z + 8}{( z + 1 ) ( z + 2 )}

\frac{z ^{2} - 6 z + 8}{z ^{2} + 3 z + 2}

Solution steps

\frac{z ^{2} - 6 z + 8}{( z + 1 ) ( z + 2 )}

Expand

(z + 1) (z + 2) : z^{2} + 3 z + 2

= \frac{z ^{2} - 6 z + 8}{z ^{2} + 3 z + 2}

8 \cdot 6

y^{\frac{1}{3}} (y^{\frac{1}{3}} - y^{\frac{3}{2}})

(1 + e^{3 x})^{2}

4 cos (θ) (8 tan (θ) + 5 sec (θ))

\frac{d ^{2}}{d x ^{2}} ((y) (x sin (x) - cos (x)))
