We are going to simplify this expression by using the orders of operations, and that says, okay, let's look at the parentheses first.
00:09
Well, inside this parentheses, those are not like terms, so we can't combine them.
00:14
We can't do anything.
00:16
Let's move on in the orders of operations.
00:18
So the next step is to say is multiplication.
00:23
So i'm going to take negative 4 times the first term in parentheses 1.
00:28
So negative 4 times 1 is just negative 4.
00:33
And then i'm going to take negative 4 and multiply it by the second term.
00:43
And the second term is this negative x here.
00:49
So i'm going to take negative 4 times negative x, and that gives me positive 4x...
