# How do you simplify #(2x-2) /(x+4 )* (x^2+4)/(x^2-3x+2)#?

##### 1 Answer

The expression simplifies into

#### Explanation:

You need to factor both numerators and denominators as much as possible, and then see if some terms cancel out.

The first numerator is easily written as

The first denominator is already of degree one, so no further factorizing is possible.

The second numerator is

The second denominator has roots that can be found via the

These numbers are obviously

Now, let's plug all the results together, writing your expression as

As you can see, the term

**PS!!**

Are you sure that the second fraction isn't

If so, you could write
