In this problem, we're being asked to square the binomial 2x squared plus 3y.
00:04
Well, this is an example of one of our special products.
00:07
It's when we're squaring the sum of a binomial.
00:10
So here's how the rule works.
00:11
It says if we have a plus b being squared, the result will be a squared plus 2ab plus b squared.
00:19
Well, a represents the first term of the binomial.
00:22
So for this problem, a will be 2x squared.
00:25
And b is the second term of the binomial.
00:28
So in this problem, it would be 3y...
