Ques: Find the least common denominator (LCD) of the pair of the complex fractionsexample of Complex Fraction.


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


    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).
