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}

(3 + 3 i)^{5}

(x + i y)^{5}

(x + Δ x)^{4}

\frac{n ^{2} ( n + 1 ) ^{2}}{4}

(- 1 + 3 i)^{4}
