Question

What is the discriminant? What does it tell you about the types of solutions you can have?

Answer 1

Explanation:

ax² + bx + c = 0

Discriminant D = [ - b ± √(b² - 4ac) ] / 2a

If D > 0, then quadratic equation has 2 real roots ;

If D = 0, then quadratic equation has 1 real root ;

If D < 0, then quadratic equation has 0 real roots .
