Question

What is the vertex form of the equation..
y=x^2-6x+8

Answer 1

You must "Complete the Square"!

y = (x^2 - 6x + _____) + 8 - _____

With what shall we fill in BOTH blanks?

Answer 2

9..

Answer 3

Yes!!! Excellent work. Put that in and simplify. Let's see what you get.

Answer 4

y=(x^2-6+9)+8-9
y=x-3^2+8-9

Answer 5

Pretty close. Missing some parentheses and go ahead and add those last two values.

\(y = (x-3)^{2} - 1\)
