Question

Which of the following equations is the result of completing the square on x^2 - 6x - 9 = 0?

Answer 1

\[(x-3)^2=0\]

Answer 2

That's right!

Answer 3

Do they need the solution, or is that it?
P.S. You were right there.

Answer 4

Hey wait.

Answer 5

\[(x - 3)^2 = x^2 - 6x + 9 \]

Answer 6

So, there's a different way.

Answer 7

\[x^2 - 6x - 9 = 0 \implies x^2 - 6x + 9 = 18 \implies (x - 3)^2 = 18\]\[\implies (x - 3)^2 - 18 = 0 \]
