To complete the square you have something like the following: $6x^2+19x=7 \implies 6(x^2 + \frac{19}{6}x) = 7$ Then you take half the x term coefficient and add it to both sides.

$x^2 + \frac{19}{6}x +\frac{19^2}{12^2} = \frac{7}{6} + \frac{19^2}{12^2}$ $\implies (x + \frac{19}{12})^2 = \frac{529}{144}$

Kind of a nasty quadratic to be doing this with though
