Example 3 illustrates that there may not be an immediately obvious substitution. In the cases that fractions and poly-nomials, look at the power on the numerator. In Example 3 we had 1, so the degree was zero. To make a successful substitution, we would need u to be a degree 1 polynomial (0 + 1 = 1). Obviously the polynomial on the denominator
