So this problem asks us to perform the indicator operations.
00:04
We have multiplication happening between the two and everything inside the parentheses over here.
00:09
We have another multiplication happening over here between the negative three and everything inside the parentheses.
00:15
And then lastly, we have a subtraction happening between these two expressions.
00:21
So what we're going to do is we're going to go ahead and simplify by first multiplying.
00:24
And we're going to go ahead and use the distributor property to distribute this two over to everything inside the parentheses.
00:32
So when we do that, remember distribute means to multiply, we're going to get 6r squared plus the 8r plus the 4.
00:43
And similarly, we're going to go ahead and distribute the negative 3 now to everything inside the parentheses.
00:53
Doing so, we get a positive 3r squared minus 12r plus 15.
01:04
Once we have simplified, we're going to go ahead and combine like terms to simplify this expression further.
01:11
So we're going to go ahead and combine the 6r square with its like term...
