## LessonEdit

To simplify rational expressions, first we need to know what they are. They are fractions that have polynomials on both their numerators and denominators.

2x6x-2^{2}+8x+8

You just can simplify **factors**, not terms. That means you have to factorize the nominator and the denominator:

2x= 6x-2^{2}+8x+8

2(x+2)2(3x-1)^{2}

Now, both are divisible by 2. So just divide them by 2, the result would be:

~~2~~(x+2)^{2}~~2~~(3x-1)
