Solve for roots:

roots:

and

vertex:
Convert to Vertex Form:
...group the first 2 terms together, separating them from the constant term
..factor out leading coefficient, for completing the square to work, the coefficient of must be
...Complete the square, Take half of coefficient and square it. Notice to keep equation balanced you must add this number and subtract it making the net effect zero.

..... vertex form; so, and
axis of symmetry is
