Frequently Asked Questions
What is the discriminant of a quadratic equation?
The discriminant is the value b squared minus 4ac, taken from the standard quadratic equation ax squared plus bx plus c equals 0.
What is the discriminant of x squared minus 5x plus 6 equals 0?
The discriminant is 1, since 5 squared minus 4 times 1 times 6 equals 25 minus 24.
What does the discriminant tell you about the roots?
A positive discriminant means two distinct real roots, zero means one repeated real root, and a negative discriminant means two complex roots.
