This question, we're given this formula here, 3t minus 2y, 3t plus 5y, and we're asked to perform the indicated operations, which would be to distribute this out and multiply these terms together.
00:19
And again, what we're going to be using is foil, which stands for first, outside, inside, and last.
00:28
So the first terms are going to refer to these three t's, and that's what we'll do for.
00:34
So we do 3t times 3t.
00:40
Now we do the outside, which would be this 3t and 5y.
00:48
Now what we get is plus 15 t.
00:53
Or actually let me redo this.
00:59
Let's rewrite this actually as 3t times 5y...
