The vertex of a parabola is at (12,-4) and its axis of symmetry is vertical. One of the x-intercepts is at (18,0). What is the x-coordinate of the other x-intercept?

One of the vertices is 6 units to the right of the vertex, so the other must be 6 to the left of the vertex.

Can you find it from here?
