A^2+b*+c=0

[plionheart]

I need to present a work until tomorrow in Visual beginner's
all-purpose symbolic instruction code.Net, that it consists of deciding the equation of 2º Degree A*^2 + B* + C =0
The environment goes to have 3 boxes of text a button and one label, each box of text corresponds to A B C of formulates, and label goes to present the result or the two results if the result
will be greater that 0.

But I need to make this on the basis of everything functions, the button to calculate goes to have very little code.

Please help me, that is very important for me, and I do not perceive very of Mathematics.

I go to leave in annex a little of the project to see as it will be the
graphical environment, and the little that I obtained to make.
