If b^2 - 4ac is a perfect square, then the roots are rational, and the quadratic can be factored.

b^2 - 4ac ==> this is the discriminant

note: for real numbers a, b and c,,

*if b^2 - 4ac < 0 : 2 imaginary roots

*if b^2 - 4ac = 0 : 1 real and distinct root

*if b^2 - 4ac > 0 : 2 real and distinct roots
