OpenStudy (bookworm14):

I was actually needing someone to check my answer for this question. I got C, but I am not 100% sure that is correct

OpenStudy (michele_laino):

correct! you have to add \(81\)

OpenStudy (anonymous):

are you solving for x or just completeing the square?

OpenStudy (captainfluffy):

are u sure its not negative?

OpenStudy (michele_laino):

hint: we have this: \(x^2-18x+81=(x-9)^2\)

OpenStudy (anonymous):

@CaptainFluffy no a negative squared is a positive

OpenStudy (captainfluffy):

ok then i was right the first time

OpenStudy (bookworm14):

I am just completing the square, I think. So you agree the answer is C ?

OpenStudy (michele_laino):

Of course!

OpenStudy (anonymous):
