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???
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.
