Okay, we're going to factor the expression given to us.
00:06
4x squared y squared plus 4xy squared plus y squared plus y squared.
00:11
First thing we look for is a common factor.
00:14
Y squared is our common factor because it's in each one.
00:17
That's all that's in common.
00:19
So then we have 4x squared plus 4x plus 1 left over.
00:26
Now we need to factor the trinomial.
00:29
I am going to use grouping for this.
00:35
So i'm going to take my first coefficient and multiply it by my last term to get four, and then i'm going to keep, you have the four in the middle, and so i'm multiplying to four and adding to four, which can only be two and two, so two times two and two plus two.
00:53
And so i rewrite my trinomial as a polynomial with four terms, and instead of four x, i've got 2x and 2x...
