how to complete a square

Hint: Since y = f(x), rewrite it like this: \(y = 3x^2 + 3x  11\) Next add 11 to both sides, then divide divide both sides by 3 to get: \(\frac{y + 11}{3} = x^2  x\) Now add \(\frac{1}{16}\) to both sides to get: \(\frac{y + 11}{3} + \frac{1}{16} = x^2  x + \frac{1}{16}\) Once you have finished reducing, you should have a new expression for y

The final result I get comes out to \(y = \large\frac{48(x\frac{1}{4}^2)  3}{16}  11\)

Ideally, I think you would want to express that as just one fraction.

Well, I did most of the work for you. You can finish the rest.

I must have made a calculation mistake because here's wolfram alpha's result: http://www.wolframalpha.com/input/?i=complete%20square%20(%5B%2F%2Fquantity%3A3%2F%2F%5D)x%5E2%2B(%5B%2F%2Fquantity%3A13%2F%2F%5D)x%2B(%5B%2F%2Fquantity%3A11%2F%2F%5D)

Yeah, I see where I went wrong. I added 1/16 to both sides instead of adding 1/4 to both sides
