Use the discriminant to determine how many real number solutions the equation has.
t^2 + 8t + 16 = 0

discriminant= b24ac
(8)^24(1)(16)
6464=0
One real root (because it equals 0).
If it was a positive number, there would be two real roots. If it was a negative number, there would be two COMPLEX roots.
