Question 37115: Please help me out with this one! I've been stuck on it for a while now. Please show all work. I would greatly appreciate any help.

A)Find the equation for the axis of symmetry.
B)Find the coordinates of the vertex.
Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!

first find the roots, if any

multiply both sides by -1

***note***
the above equation with the signs reversed is ONLY for finding
the roots - it is not for anything else - the actual equation is
the one you started with
****************
the roots are +3 and +1
those are the values for x that make the above true
the axis of sym will be in the middle of the roots

The equation of the axis of symmety is x = 2
The vertex is on the axis of symmetry, so
find what y is when x = 2

So, the vertex is at (2,1)
