for \(ax^2+bx+c=0\) the discriminant is \(\Delta = b^2-4ac\)
UnkleRhaukus

when Δ is positive there are two real solutions when Δ is zero there is one real solution when Δ is negative there are two complex solutions (a complex number has a real and an imaginary part )

if you had to find these solutions, then you would use quadratic formula \[\frac{-b\pm\sqrt \Delta}{2a}\] i guess your solutions would be purely imaginary only when \(b=0\)
