Ques:
Find the least common denominator (LCD) of the pair of the complex fractions.
Choices:

A. (x + 7)(x + 8)
B. (x + 8)
C. (x + 15)
D. (x + 56)
Correct Answer: A
Solution:

Step 1: Find the highest power of each factor that appears in either denominator.
Step 2: Both (x + 7) and (x + 8) are linear factors.
Step 3: So, the LCD of the given two complex fractions is (x + 7)(x + 8).
