Quizplus · Accepted Answer

The least common denominator (LCD) of two fractions is the least common multiple (LCM) of their denominators. For the fractions $\frac{3}{x}$ and $\frac{3}{x+6}$, the denominators are $x$ and $x+6$, respectively. Since these two expressions have no common factors other than 1, the LCD is simply their product, $x(x+6)$.
