Question 469726: help please
Use the discriminant to determine the number of real solutions of the equation.
5x^2-3x+1=0 Answer by ccs2011(207) (Show Source):
You can put this solution on YOUR website! The discriminant, D is as follows:
given quadratic equation
D =
If D = 0, then there is only 1 real solution, specifically x = -b/2a
If D > 0, then there are exactly 2 real solutions
If D < 0, then no real solutions exist, graph never crosses x-axis
For this equation
a = 5
b = -3
c = 1
D = = =
-11 < 0
Therefore, no real solutions exist for this equation
