expand 6/((s^2+4s+20)^2)

expand

\frac{6}{( s ^{2} + 4 s + 20 ) ^{2}}

\frac{6}{s ^{4} + 8 s ^{3} + 56 s ^{2} + 160 s + 400}

Solution steps

\frac{6}{( s ^{2} + 4 s + 20 ) ^{2}}

(s^{2} + 4 s + 20)^{2} = s^{4} + 8 s^{3} + 56 s^{2} + 160 s + 400

= \frac{6}{s ^{4} + 8 s ^{3} + 56 s ^{2} + 160 s + 400}

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

(x + 3)^{2}

(x + 2) (x - 2)

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

(1 - i)^{7}
