In this problem, what we're being asked to do is to simplify the given expression.
00:04
Remember, when you simplify expressions in your final answer, you cannot have any more late terms that can be put together.
00:11
So if i'm looking for like terms here, i'm going to have all the terms to have a z.
00:16
Those will be like terms.
00:17
So we're going to start by grouping those together.
00:19
So the like terms we have are 5z, negative 7z, and negative 3z.
00:24
So we'll group these together.
00:26
So we'll have 5z minus 7 z, minus 3z, and then our last term, positive 2, our constant, doesn't have a like term, but we still need to bring it down for our answer...
