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

expand

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

\frac{2 x - 1}{s ^{5} + 3 s ^{4} + 3 s ^{3} + s ^{2}}

Solution steps

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

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

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

Expand

s^{2} (s^{3} + 3 s^{2} + 3 s + 1) : s^{5} + 3 s^{4} + 3 s^{3} + s^{2}

= \frac{2 x - 1}{s ^{5} + 3 s ^{4} + 3 s ^{3} + s ^{2}}

4 a^{2} (a - b) (a + b) + b^{4}

(x + y) (d + c + e)

\frac{x}{( 14.4 - x ) ^{4}}

\frac{5 x + 12}{x ( x - 7 ) ( x + 3 )}

5 (x + 9 = x - 3)
