choices?

nincompoop · Answer

do you know how to complete the square?

anonymous · Answer

There are no choices
and i got an answer but webassign says it's wrong

nincompoop · Answer

we can solve it without relying on options or choices :)

nincompoop · Answer

show me how you would complete the square

anonymous · Answer

I got  2(x-6)^2-17

anonymous · Answer

i just youtubed it so I know I did it the way instructed

nincompoop · Answer

will you show me how you did that?

anonymous · Answer

okay sure. she said I needed to complete the square so from the first formula I did this. I grouped these together (2x^2-12x+36) +19-36
Then that turned into my answer after factoring

anonymous · Answer

i got the 36 from taking (12/2)^2

nincompoop · Answer

okay that is not the proper way... you jumped and skipped one too many steps :)

anonymous · Answer

the 19 is in the original. and the negative 36 is to "cancel the  36 in the middle"

anonymous · Answer

I'll see if I can find the video and show you

anonymous · Answer

I'm a college kid, I don't have much money to spare. Life is unfortunate yes
