 Question 56848: Put the following function: y=x^2-6x+8 in the form y=a(x-h)2=k Any advice on how to find this would be great! I tried to follow the instructions given by the book but it did not work out so well! It says to find the answer by completing the square. I tend to get lost in that process when you add the 8 to both sides.Answer by stanbon(57410)   (Show Source): You can put this solution on YOUR website!Put the following function: y=x^2-6x+8 in the form y=a(x-h)2+k ---------------- Rewrite as: y-8+? = x^2-6x+? To complete the square you need (-6/2)^2=9 Put that in place of the ? to get: y-8+9=x^2-6x+9 Rewrite as: y+1 = (x-3)^2 Then: y=(x-3)^2-1 Cheers, Stan H.
