Rational Function into Partial Fraction

HI Looking to make 72/36s+s^3 into partial fraction. 
 
Can find the value of A ok but can't seem to cancel out A value to find B. Expanding the denominator I got s(s^2+36), then when I come to cancel out A value a squared value + 36 will not =0.
 
Thanks for your help in advance.
 
Michael

I think that is a very laudable tactic, although that isn't usually what people want.

What is the point of factoring s^2 +36 using complex numbers, especially if this is a Laplace Transform?

You don't wqnt to factor the irreducible quadratic factors in a denominator, using complex numbers!
