Evaluate the discriminant , hence the roots are two distinct real numbers. Also note that
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
10x^2-x-2=0
a = 10, b = -1, c = -2
------------------------
b^2-4ac = 100-4*10*-2 = 180
---
Since b^2-4ac > 0 there are
2 Real Number solutions.
