One way is to use the quadratic formula.
ax² + bx + c = 0
Formula: [-b ± √(b² - 4ac)] / 2a

Factorize quadratics anytime you can... you're less likely to make an arithmetic error than in using any other method. Use the quadratic formula or complete a square only if you can't find the proper binomial factors within a minute or so.

this order
with the carpenter's eye ( x^2 - 5 = 0 )
factorisation.
put eq in quadraticform (aX + b)^2 = c
and if you are stupid you can always use the abc formula

Very simple...if your can't factor it right off the bat the just use the quadratic formula...very simple..most importantly, just don't overcomplicate it!!!

If you see how to factor it right off, go for it.
If not, use the quadratic formula.
