Question

Hey guys, how can I factorise quadratic expressions using the completed square form???

I'm not exactly sure what you mean, but this link should help!

:) and in terms of factoring, I always think backwards a bit. I use FOIL in order to factor it and to go from expression to original form, I think backwards with FOIL if that makes sense:)
