The first thing you need to do is to put your equation into standard form, namely: 
So just add 
to both sides
The quadratic formula is:
So just plug in the values of the coefficients:
\pm sqrt{(4)^2-4(3)(20)}}{2(3)})
And do the arithmetic.
The discriminant (the part under the radical) is negative in this case, so you will end up with a conjugate pair of complex roots. Just factor -1 out of the radicand and take out an 
which is defined as
