Take 1/2 of the coefficient of x and square it. Add that to the x^2 and x term (which is really subtracting it since there is a minus sign outside the parentheses) so then add it again.

There is an alternate way that might be easier. The x coordinate of the vertex is -b/2a. Calculate that then plug it back in to find the y coordinate. The axis of symmetry is the vertical line that goes through the vertex.
