State the solutions, or estimated solutions, to each quadratick equation. We have

equation is x^2-9x+20.25=0 and the graph is y=x^2-9x+20.25

Not sure how to figure this one out. I assume I just solve the equation and not the graph to get the ordered pairs?

If you use the Quadratic Formula, you

will notice that the value under the radical = 0:

B^2 = 4AC = 81,

B^2 - 4AC = 0,

Therefore, X = -B / 2A = 9 / 2 = 4.5.
