-----------------------------
vertex of a quadratic is at (3, 16) and one of the zeros is at (-1, 0)
What is the coordinate of the other zero?
--------------------------

If want vertical symmetry axis,

FOR THE OTHER ZERO: symmetry axis x=3, is 4 units away from one of the zeros given (-1,0). The OTHER zero is at x=7. Other zero is (7,0).
