Find the LCD of the given rational expressions.
-$\frac { 9 } { 4 x } , \frac { 4 } { 6 x ^ { 2 } }$
A) $12 x ^ { 2 }$
B) 12
C) $12 x ^ { 3 }$

Quizplus · Accepted Answer

To find the LCD, we need to factor the denominators and take the highest power of each factor. The factors of $4x$ are $2$, $2$, and $x$ and the factors of $6x^2$ are $2$, $3$, $x$, and $x$. Thus, the LCD is $2 \cdot 3 \cdot 2 \cdot x \cdot x = \boxed{12x^2}$.
