I have got the equation

$\displaystyle 10/(s^2+s+10)$

I want to write it in this form

$\displaystyle b/((s+a)^2+b^2)$

My efforts are these:-

I took the denominator

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

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)
