Question
Find the least common denominator of the rational expressions.$$\frac{3}{x-6} \text { and } \frac{4}{x^{2}-36}$$
Step 1
The denominator of the first expression is already in its simplest form, i.e., $x-6$. The denominator of the second expression is a difference of squares, which can be factored as $(x-6)(x+6)$. Show more…
