I have a test in algebra 2 tomorrow and i just got back from thanksgiving break abd forgot how to do these.
here is the problem:

x^2= 6x - 8

I need to graph and find the exact roots.

$x^2-6x+8=0$
To sketch the graph, I would write the quadratic in vertex form $y=(x-h)^2+k$ by completing the square.
