    Need help i am new in perl...

    I have to write a programme. Whic is like this:

    You are write a program whcih uses the quadratic equation to solve second-order polynominal. wchich is
    a x**2 + b x + c =0

    and use the quadratic equation, when given value for the coefficient a, b and c, to find the value of x for which the equation is true the quadratic equation is

    -b +- sqrt (b**2 -4ac)
    X = --------------------------------------------
    2a
    program should prompt for the value of cofficients a, b and c from the user and the output the solutions. The interaction with the user might look like this:

    Input value for the cofficient a: 2
    Input value for the cofficient b: 5
    Input value for the cofficient c: 1

    The possible value for x are :
    -0.2192235935955 85
    -2.2807764064044 2

    please help me out
    thankx in advance

          This makes at least two forums this question is posted on. I expect the count to rise as I check other forums.

              I fully agree! We cannot do your homework for you, but we can help you if you get stuck. You have to do the coding legwork though.

                      He's forum shopping for the answer, posting the same question on multi-forums (up to three now that I have seen). I recommend you delete this thread, this person does not want help, he wants the answer coded and ready to turn in for a grade.
