Two unknowns

  1. Mar 24, 2005 #1
    In the equation [tex]4x^2+kx+1=0[/tex] I'm supposed to find the value of k. But since there are two unknowns, it is only possible to find k expressed as a function of x right...?

    Correct. Solve for k in terms of x, unless they said something like when x= 1 etc....

    Indeed. Make sure they haven't given you any other information that might help.

    State the text of the problem in the original form.I can't believe it can be that simple...

    Well that's a quadratic set-up there; it seems to me that you would solve for x in terms of k, but that's really the same thing isn't it?
