expand 2/((s-1)^2(s-3))

expand

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

\frac{2}{s ^{3} - 5 s ^{2} + 7 s - 3}

Solution steps

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

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

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

Expand

(s^{2} - 2 s + 1) (s - 3) : s^{3} - 5 s^{2} + 7 s - 3

= \frac{2}{s ^{3} - 5 s ^{2} + 7 s - 3}

\frac{n ! ( n + 2 )}{( n + 1 )}

\frac{( x ( x - 10 ) )}{x + 13}

x - 6 \cdot 7 x^{2}

t er m s (4 + 7 a^{2})^{2}

- \frac{1}{( x ^{2} - 1 ) x}
