I agree. Unless the coeffiecients are relatively small, I usually don't waste too much time trying to factor it.
If the x^2 term has a coefficient of 1, and the x term is even I ALWAYS complete the square, it is much faster than the formula. Otherwise,
I do a quick calculation of √(b^2 - 4ac)
If I get a whole number, I know it would have factored, but I am almost done anyway, so I finish with the formula.
for this one:
x = (123 ± √15033)/16

I think he means 13x, not 123x.
