What sort of solutions are found when 
No real solutions
Look at the discriminant to figure out the number of solutions.
For this equation,
Since the discriminant is positive, this means that there will be 
Example Question #32 : Ged Math
Sarah says 3 is a rational number. Tom disagrees and says 3 is an integer. Who is right?
Tom
42
Sarah
Neither
Both
Both
