Solve by completing the square: $3x^2 - 6x - 5 = 0$

OpenStudy (anonymous):

OK

OpenStudy (anonymous):

$3x^2-6x=5$ $x^2-2x=5/3$ $(x-1)^2=5/3 +1$ $x-1=\pm \sqrt{(8/3)}$ $x=1\pm \sqrt{8/3}$

you failed to complete the square...

OpenStudy (anonymous):

why?

OpenStudy (anonymous):

completing the square means that you take b/2 and square it to get c...

I am pretty sure that I did what the question asked

OpenStudy (anonymous):

completing the square is not shown in your work. you moved the 5 to the other side and divided by three. this is not completing the square

completing the square would start like: ${-6 \over 2}, -3^2 = 9$
