Use the discriminant to determine whether the following equations have solutions that are: two different rational solutions; two different irrational solutions; exactly one rational solution; or two different imaginary solutions.
x2 = 5x + 6

x^2  5x  6 = 0
discr. = 25  4(1)(6) which is positive, so you have 2 different real roots
