Okay, number 25.

This is the first one in this set of problems of many, right? this is a long set of problems, simplifying all these expressions.
00:15
And we're going to bring back all of our old algebra techniques, all the factoring and special products and all that stuff.
00:24
You're going to be.
00:26
You have to be remembering all of those things as you navigate through this set of problems.
00:31
This one, however, very easy to do.
00:33
You'll notice in the numerator we can divide out a three from both of those terms okay this is just basic monomial factoring that's it right and in the denominator you might notice that both of these terms can be are divisible by four so let's do that we're going to just do monomial factoring if we factor out a three from the top we'll be left with a plus two right you distribute that and you get three a plus six and in the denominator, if we factor out of four, lo and behold, we are also left with a plus two.

Okay.

Now, a lot of common errors occur in thinking that, well, sorry, let me fix that eight, and thinking something like this...
