Find the lowest common denominator of the following fractions.
A.) 24y2
B.) 24(y2 - 1)
C.) 24(y2 - 1)(y + 1)


Answer:
B.) 24(y² -1)
Step-by-step explanation:
The denominator of the first fraction is 2³(y +1).
The denominator of the second fraction is 2·3(y +1)(y -1).
The LCD is the product of the unique factors to their highest powers:
2³·3·(y +1)(y -1) = 24(y² -1)
