expand (s-1)/((s-2)*(s+1))

expand

\frac{s - 1}{( s - 2 ) \cdot ( s + 1 )}

\frac{s - 1}{s ^{2} - s - 2}

Solution steps

\frac{s - 1}{( s - 2 ) ( s + 1 )}

Expand

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

= \frac{s - 1}{s ^{2} - s - 2}

\frac{y + 6}{y ^{2} ( y + 1 )}

\frac{0.5 x}{( x - 0.5 ) ( z - 1 )}

\frac{8 ( s ^{6} + 4 s ^{4} + 10 s ^{2} + 8 )}{s ^{3} ( s ^{2} + 4 ) ^{3}}

\frac{( - 10 x ^{2} + 24 x + 152 )}{( x ^{2} - 4 x + 20 ) ^{2}}
