Answer 1

Answer:

The discriminant determines the nature of the roots of a quadratic equation. The word 'nature' refers to the types of numbers the roots can be — namely real, rational, irrational or imaginary. Δ is the Greek symbol for the letter D. If Δ<0, then roots are imaginary (non-real) and beyond the scope of this book.
