    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.

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