Here, we're given an expression that we want to simplify.
00:03
The first step is just to factor everything.
00:06
So this first part, we have x plus 2 times x plus 1.
00:11
And then on the bottom, we're going to get a 2x plus 2, sorry, 2x minus 5, and a x plus 2.
00:27
That's the first part.
00:28
The next fraction, we're going to pull out a 2x squared, and we're left with a 1 plus 2x.
00:35
And then on the bottom, and we'll pull out an x, and we're left with x plus 3.
00:47
Now for the next one, we're going to divide, which means multiply by the reciprocal, so let's do x over x plus 2 times x plus 1.

I just flipped it and also factored it...
