  1. just in general

    when I'm asked to sovle for X in a equation that is set to zero it's not really set to zero at all is it???

    X^2 + 4X - 1 = 0

    really what this is saying

    X^2 + 4X - 1 = dy

    right???

  2. The solution to
    X^2 + 4X - 1 = 0
    is
    -2±√5

    The equation is a quadratic in x.

    If the equation is given as
    X^2 + 4X - 1 = dx
    it is missing something, because dx is a differential quantity while the left hand side is a full quantity.

    Can you check your question and post again.

    You can also help by telling to which course the question belongs, Calculus I, II or III or algebra.
