Quadratic Formula

This lets you input A, B, and C. Then it takes those variables and plugs them into the equation:

-b  sqrt( b - 4AC )
---------------------
         2A

If b - 4AC is < 0: No real solutions
If b - 4AC is = 0: One real solution
If b - 4AC is > 0: Two real solotions

When the program is finished returning the solutons, it will give you a menu that has these options:

[VRTX|GRPH|RNGE|AGAIN|EXIT]

VRTX gives you the vertex of the parabola.
GRPH graphs the parabola.
RNGE set the range of the graph.
AGAIN lets you input a new set of A, B, and C.
EXIT stops the program.
