    simple Math prob. how to colculate?

    Sups,
    I'm sorry, but i dont know the english word for it, but i'm tryin to write a lil app which will colculate 'functions' like 2x*x + 5x + 3.
    which goes like this:
    x1,2 = (b*b something (-4)*a*c) /2
    I hope u guys knows what i'm talkin about
    well, my question is how can i colcuate the 'other' action of b*b?
    sorry, bad english. PLZ CHECK attachment for a picture.
    tnx!

    x1=(b*b +sqr( (-4)*a*c)) /2
    x2=(b*b -sqr( (-4)*a*c)) /2

    Hope this helps,
