since the roots involve -b±√(b^2-4ac)
if the discriminant is negative, there are no real roots.
see what you can make of the other cases
Or, heck -- read your text or use google
The b2 − 4ac part of the formula is called the discriminant. What happens if the discriminant is
greater than 0?
equal to 0?
less than 0?
