simplify 1+1/(s(s+2.2))

simplify

1 + \frac{1}{s ( s + 2.2 )}

\frac{s ^{2} + 2.2 s + 1}{s ( s + 2.2 )}

Solution steps

1 + \frac{1}{s ( s + 2.2 )}

Apply the fraction rule:

1 + \frac{b}{c} = \frac{c + b}{c}

= \frac{s ( s + 2.2 ) + 1}{s ( s + 2.2 )}

Simplify

s (s + 2.2) + 1 : s^{2} + 2.2 s + 1

= \frac{s ^{2} + 2.2 s + 1}{s ( s + 2.2 )}

\frac{2 y ^{5} x - 3 y ^{3} x ^{2} - y x ^{4}}{( x ^{2} + y ^{2} ) ^{2}}

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

\frac{d}{d z} ((w) (3 z^{7} - 7 z^{3} + 21 z^{2}))

e^{x (x - 9)}

\frac{- 8 x sin ( x ) - 8 cos ( x )}{( cos ( x ) + 4 x ) ^{2}}
