connection to another class

This last week we have been talking about completing the square and vertex form and I remember doing a lot of that in precalc coordinate geometry which I took last year. In coordinate geometry I remember completing the square was a little hard to figure out at first but eventually became very easy. Since I've taken that class I completely forgot how to do it but after this last week it's all coming back to me. I really enjoyed taking coordinate geometry last year and I hope that the rest of this year goes as well as that did.
