X-coordinate of the vertex of a parabola. It corresponds to
the position of the symmetry axis that is defined by the
graph of the quadratic formula. X = -b/2a is the "center" of
the parabola defined by a quadratic equation. Plug this in to
a quadratic formula to solve for the vertex.

To remove a radical from an equation by squaring, you can
square both sides of the equation, raising each side to the
power of the index. The square root function is the inverse
of the squaring function, so squaring both sides will cancel
out the radical.
