Given quadratic equation

$x^2+6x+6=0$
Using the usual conventions,
a=1, b=6, c=6
Apply the quadratic formula,
$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$
substitute a,b & c with numerical values,
$x=\frac{-6\pm\sqrt{6^2-4(1)(6)}}{2(1)}$
simplify:
$x=\frac{-6\pm\sqrt{12}}{2}$

Basically ur just looking for the LCM (lowest common multiple) of all of these numbers.

3,7,12,14....lowest number that all 4 of these numbers go into evenly is 84.

so they will ring together next in 84 minutes (1 hr 24 minutes) making it 5:24 a.m.
