Question 234186
I need to use the discriminant to determine the number of solutions of the quadratic equation, and whether the solutions are real or complex. (it is not necessary to find the roots; just determine the number and types of solutions) 
x^2 + 6x - 7 = 0
------------------------
discriminant = b^2-4ac
= 6^2-4*1*-7
= 36+28
= 64
-----------
Since the discriminant is positive, the quadratic
has 2 unequal Real Number solutions.
