6x^2+11x+15using the quadratic equation we get
x=(-b+-sqrt[b^2-4ac])/2a
x=(-11+-sqrt[11^2-4*6*15])/2*6
x=(-11+-sqrt[121-360])/12
x=(-11+-sqrt-239)/12
x=(-11+-[-15.4596i])/12
x=(-11-15.4596i)/12
x=(-11/12)-15.4596i/12
x=-.916666-1.2883i
x=-.916666+1.2883i

factor: 6x^2+11x+15
Use the quadratic formula to get:
x=[-11+-sqrt(11^2-4*6*15)]/12
x=[-11+-sqrt(-239)]/12
x=-11/12 +[(sqrt239)/12]i or x=-11/12 -[(sqrt239)/12]i
The factor form is:
(x+11/12 -[(sqrt239)/12]i)*(x+11/12 +[(sqrt239)/12]i)
