Hi guys im having troule with getting the Two real roots: -2.0, 2.5
heres the the assignment

Write a program that prompts the user to enter values for a, b, and c and displays the result based on the discriminant. If the discriminant is positive, display two roots. If the discriminant is zero, display one root. If the discriminant is negative, display "The equation has no real roots".

Examples:

1 2 1

One real root: -1.0

1 1 1

No real roots

2 -1 -10

Two real roots: -2.0, 2.5

Line 14: write a minus sign after the -b instead of a plus sign.
