How do you write the Vertex form equation of the parabola #y=x^2-6x+5#?
Please see the explanation.
The vertex form of a parabola of this type is:
The first step is to add 0 to equation  in the form
If we expand the square in equation ,
Solve for h:
Substitute 3 for every h:
Simplify the constant terms:
This is the vertex form.
