Discriminant – the (b²  4ac) in the quadratic formula
 The value of (b²  4ac) tells how many solutions or xintercepts the quadratic equation will have.
 If (b²  4ac) > 0, there are two real solutions or xintercepts.
 If (b²  4ac) = 0, there is one real solution or xintercept.
 If (b²  4ac) < 0, there are no real solutions or xintercepts.
