simplify 1+(1.7(s+2)K)/(s^2+2s+1.81)

simplify

1 + \frac{1.7 ( s + 2 ) K}{s ^{2} + 2 s + 1.81}

\frac{s ^{2} + 2 s + 1.81 + 1.7 sK + 3.4 K}{s ^{2} + 2 s + 1.81}

Solution steps

1 + \frac{1.7 ( s + 2 ) K}{s ^{2} + 2 s + 1.81}

Apply the fraction rule:

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

= \frac{( s ^{2} + 2 s + 1.81 ) + 1.7 ( s + 2 ) K}{s ^{2} + 2 s + 1.81}

Apply rule:

(a) = a

(s^{2} + 2 s + 1.81) = s^{2} + 2 s + 1.81

= \frac{s ^{2} + 2 s + 1.81 + 1.7 ( s + 2 ) K}{s ^{2} + 2 s + 1.81}

Simplify

s^{2} + 2 s + 1.81 + 1.7 (s + 2) K : s^{2} + 2 s + 1.81 + 1.7 sK + 3.4 K

= \frac{s ^{2} + 2 s + 1.81 + 1.7 sK + 3.4 K}{s ^{2} + 2 s + 1.81}

\frac{( x - a ) x + 2 a ^{2}}{( x + a ) x - 2 a ^{2}}
