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

expand

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

\frac{s ^{2} - 3 s + 2}{s ^{2} + 3 s + 2}

Solution steps

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

Expand

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

= \frac{( s - 1 ) ( s - 2 )}{s ^{2} + 3 s + 2}

Expand

(s - 1) (s - 2) : s^{2} - 3 s + 2

= \frac{s ^{2} - 3 s + 2}{s ^{2} + 3 s + 2}

(2 x y^{2} + 2 y) + (2 x^{2} y + 2 x) y^{'} (x)

(vx + x x^{2} - v^{2}) d x - x (v d x + x d v = 0)

(2 + x - 1) (2 + x - 1)
