Answer:
The answer is:
which agrees with the last answer option (D) in the list.
Step-by-step explanation:
In order to add rational expressions, we need to express them with the same denominator. Therefore we examine what factors there are in the first denominator, which happens to be a difference of squares which is readily factored out as:
the second denominator consists of only one of these factors: , then in order to express both rational expressions with the same common denominator, we multiply numerator and denominator of the second fraction by the factor:
Then we get two expressions that can be easily added as shown below:
