    Cool Anybody interested in a Quadratic Solver?

    I programmed one. Simple, i know, but it does the job

    Let me know what you guys think of it.

    EDIT: Download Math Tool 3.5 here

    No it uses the \frac{ -b \pm \sqrt{b^2 - 4ac} }{2a} formula.

    I guess only kids in lower grades might find it useful then... *sigh*

    i realize that you used the quadratic formula. couldn't you alter the code to recognize complex roots though?

    as in tell the program that if it gets \sqrt{-2} for example, it should interpret it as \sqrt{2}~i. would that be too hard?

    i never checked, how does it deal with double roots? that is, when what's under the square root sign is zero?

    Okay, i got it to calculate complex roots.

    I was wondering if i could put a link to MHF up on it? Would that be okay?

    EDIT: I guess everyone would like to see first. See the attached pic
