    Help for Completing Square method

    I have got the equation

    10/(s^2+s+10)

    I want to write it in this form

    b/((s+a)^2+b^2)

    My efforts are these:-

    I took the denominator

    (s+a)^2+b^2 = (s+1/2)^2+9.75

    by completing square method

    but now i am stuck up due to numerator

    Kindly help me

    And thanks to Fantastic ( i have learnt Latix as well little bit)

    Dear moonnightingale,

    s^2+s+10=(s+\frac{1}{2})^2-\frac{1}{4}+10

    Hope you can continue.

    s^2+s+10=(s+\frac{1}{2})^2-\frac{1}{4}+10=(s+\frac{1}{2})^2+\frac{39}{4}

    Therefore, \frac{10}{s^2+s+10}=\frac{10}{(s+\frac{1}{2})^2+\f  rac{39}{4}}
