We begin by trying to find a common denominator for these two fractions....

1) The two denominators that we are working with are

2) To find the LCD we must factor out the two numbers

3) Then we find the product of each factor with the highest power

Then we try to set each denominator to the LCD that we found

4)

Now since we have a common denominator, we can now simply the equation into one fraction

That took forever to write out on this,,,
