There's actually separate ways to rewrite this.
00:02
I actually call standard form, vertex form.
00:08
And that came to my attention that other people have different names for these.
00:12
But one way to approach this is to just divide out a three of the first couple terms.
00:22
So what i'm going to do is just move this one over.
00:25
And what i need to do then is divide this term by three.
00:31
And notice where i stop my parentheses, and that's why this one doesn't change.
00:36
I'm going to put a blank here and a blank here.
00:40
And some people will say to take this number divided by two, it actually might make sense if you multiply by one half, and then square that number.
00:50
So we're looking at negative one -six, half of one -third, and then when you square it, you get positive 1 over 36.
01:02
But technically speaking, i'm not adding just 1 over 36...
