expand (18)/((s^2)(s^2+9))

expand

\frac{18}{( s ^{2} ) ( s ^{2} + 9 )}

\frac{18}{s ^{4} + 9 s ^{2}}

Solution steps

\frac{18}{( s ^{2} ) ( s ^{2} + 9 )}

Remove parentheses:

(a) = a

= \frac{18}{s ^{2} ( s ^{2} + 9 )}

Expand

s^{2} (s^{2} + 9) : s^{4} + 9 s^{2}

= \frac{18}{s ^{4} + 9 s ^{2}}

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

(80.2 \cdot e^{- 4 t} + 8.2) d t

- 3 (a + 4 = - 2 a + 4)

\frac{( t x + t ) ^{2}}{4}

(1 + cos (2 θ)) 3 = sin (2 θ)
