You can put this solution on YOUR website! 2x^2+6x+9=0 (finding the value of the discriminant) How many real solutions are there of this equation?
-------------
You have a quadratic equation with a=2, b=6, c=9
-----------
The discriminant is b^2-4ac.
-------------------------
Your Problem:
b^2-4ac = 36-4*2*9 = -36
---------------
Since the result is negative, there are no Real Number
solutions to your problem.
