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

expand

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

\frac{3 s ^{2}}{s ^{4} + 2 s ^{2} + 1}

Solution steps

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

(s^{2} + 1)^{2} = s^{4} + 2 s^{2} + 1

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

+ (- x sin (y)) (y + d y)

\frac{x}{( x - 7 ) ( x + 2 )}

3 (2 x + 4 = 54)

(3 - x)^{2} + co n s tan (t) e

\frac{3 ( u + 6 )}{u - 6}
