4 x^2 + 3 x + 8 = 0
the nature of the discriminant determines the type of solutions
b^2 - 4 a c = 9 - 32 = -23 ... negative and not a perfect square
... the solutions are imaginary , two complex conjugates

4 x^2 + 3x +8 = 0
b^2-4ac = 9 - 128
Negative so solutions are complex
b^2-4ac = 9 - 128
Negative so solutions are complex
