All right, this is the problem just as it's given to us in the book.
00:05
And so as we're looking to simplify here, the first thing that i'm noticing is numbers outside of a set of parentheses.
00:13
And so that's always a good tip off, excuse me, that you're needing to distribute to multiply those by each of the sets of parentheses there.
00:23
So i think the easiest way to do this is just kind of do the little rainbow thing.
00:30
But we're going to do 7 times y squared, 7 times negative 5y, and 7 times 3.
00:41
So that's kind of our first set.
00:44
And then negative 4 times 3 would be negative 12.
00:48
Negative 4 times a negative y squared would be plus 4 y squared.
00:54
So at that point, we've taken care of all of our multiplication that we need to do.
01:01
So we will proceed by just adding and subtracting...
