expand-(s^2-4s-1)/((s-4)(s-2))

expand

- \frac{s ^{2} - 4 s - 1}{( s - 4 ) ( s - 2 )}

- \frac{s ^{2} - 4 s - 1}{s ^{2} - 6 s + 8}

Solution steps

- \frac{s ^{2} - 4 s - 1}{( s - 4 ) ( s - 2 )}

Expand

(s - 4) (s - 2) : s^{2} - 6 s + 8

= - \frac{s ^{2} - 4 s - 1}{s ^{2} - 6 s + 8}

\frac{1}{( s + 1 ) ( s ^{2} + 4 - 2 s )}

\frac{( X - 11 ) ^{2}}{2}

- \frac{2 ( 3 + 2 3 )}{3}

\frac{4}{( x + 5 ) \cdot ( x - 4 )}
