So this is 6 times x plus 2 times x plus 1. When you take the product there, you'll get x squared plus 3x plus 2, and then all of that over x plus 2 times x minus 2. Now, if we know that x does not equal negative 2, then we can divide both the numerator and the denominator by x plus 2. The reason why I'm making that constraint is that if x were to be equal to negative 2, then x plus 2 is going to be equal to 0. And you won't be able to do that. You can't. We don't know what it means to divide something by 0.
