All right, so we're going to simplify this by doing our distributive property and combining like terms.
00:09
So first, what i'm going to do is get rid of these parentheses by doing our distributive property.
00:16
Always remember that when you're doing distributive property, that the sign that is in front of the number you're distributing is connected to it.
00:25
So not only are you multiplying it by three, you're also multiplying it by a negative as well.
00:31
Or your idea of you're changing the sign of everything inside of the parentheses as well.
00:39
So make sure you keep that in mind.
00:42
That's a very common mistake that gets made.
00:49
Once i have distributed, i can drop those parentheses and continue with my problem.
00:58
So next i have distributive property again because i have to distribute that negative amongst the terms that are inside of these brackets before i can continue.
01:10
So here we are.
01:14
Right, just changing all of the signs.
01:27
All right...
