Make the given changes in the indicated examples of this section and then solve the resulting problems.

In Example 3, change the first denominator to 4x − 10 and do the multiplication.

Data from Example 3

Here, the common factor is 2(x + 3). It is permissible to multiply out the final form of the numerator and the denominator, but it is often preferable to leave the numerator and the denominator in factored form, as indicated.
