To solve by completing the square, what needs to be moved in this equation? x2 = 9 - 4x

A. The x^2

B. =

C. The - 4x

D. The 9

To complete the square, we need to have the equation set up like this:

x^2 +4x =9

To do that, we'd need to move the 4x to the left side producing

4x + x^2 = 9

And that can be rewritten as

x^2 +4x =9

So the term that needs to be moved is -4x
