All right, so here we want to match the correct polynomial in factored form, which is on our left side here, with the polynomial in the developed form over here on the right -hand side.
00:12
All right, so what we're going to do is we can do a couple of things.
00:18
We can either try to factor over here on the right and see which one matches on the left, or we can multiply out on the left, and usually that's a little bit easier to do is that multiplying out.
00:29
All right, so with this first one here, that's a binomial squared.
00:33
So that's just whatever's in the parentheses times itself again.
00:37
And then we can just double distribute to see what we get.
00:40
So x times x is x squared.
00:42
X times 3 is 3x.
00:45
3x times x is 3x.
00:48
And 3 times 3 is 9.
00:49
So these are like terms.
00:51
I can combine them.
00:52
So i'm going to have x squared plus 6x plus 9...
