expand 1/((s^2+a^2)*(s^2+b^2))

expand

\frac{1}{( s ^{2} + a ^{2} ) \cdot ( s ^{2} + b ^{2} )}

\frac{1}{s ^{4} + b ^{2} s ^{2} + a ^{2} s ^{2} + a ^{2} b ^{2}}

Solution steps

\frac{1}{( s ^{2} + a ^{2} ) ( s ^{2} + b ^{2} )}

Expand

(s^{2} + a^{2}) (s^{2} + b^{2}) : s^{4} + b^{2} s^{2} + a^{2} s^{2} + a^{2} b^{2}

= \frac{1}{s ^{4} + b ^{2} s ^{2} + a ^{2} s ^{2} + a ^{2} b ^{2}}

\frac{d ^{2}}{d y ^{2}} ((f (x)) (x (y - sin (y))))

\frac{4 x ^{2} - 24 x - 52}{( x - 3 ) ^{2}}

(2 i + 1)^{3} - (2 j + 1)^{3}

4 x - 2 (x - 2 = - 9 + 4 x + 7)

3 y^{2} (1 - x)^{3} + e^{- x}
