Question:
Make the given changes in the indicated examples of this section and then solve the resulting problems.
In Example 10, change the numerator to 2x4 − 32x2 and then simplify.
Data from Example 10
Again, the factor 4 − x has been replaced by the equivalent expression −(x − 4). This allows us to recognize the common factor of x − 4. Also, note that the order of the terms of the factor 5 + 3x was changed in writing the third fraction. This was done only to write the terms in the more standard form with the x- term first. However, because both terms are positive, it is simply an application of the commutative law of addition, and the factor itself is not actually changed.
