The discriminant can be used to determine the number and type of solutions a quadratic equation has the following types of solutions

Discriminant....................................................Number and Type of Solutions
Positive, and the square of an integer..............2 rational solutions
Positive, but not the square of an integer.........2 irrational solutions
Zero .....................................................................1 rational solution
Negative..............................................................2 non-real complex solutions

given:

use discriminant to find
....in this case we have 1 rational solution
