![**Rational Expressions: Finding the LCD of Rational Expressions with Linear Denominators**
In this exercise, you are tasked with finding the least common denominator (LCD) of the following rational expressions:
1. \( \frac{4x}{x+6} \)
2. \( \frac{1}{6x} \)
**Steps to Find the LCD:**
1. **Identify the Denominators:**
- The denominators are \( x+6 \) and \( 6x \).
2. **Factor Each Denominator:**
- \( x+6 \) is already in its simplest linear form.
- \( 6x \) is also in simplest form, with a factor of 6.
3. **Determine the LCD:**
- The LCD must include all unique factors from both denominators.
- Combine \( (x+6) \) and \( 6x = 2 \cdot 3 \cdot x \).
- The LCD is the product \( (x+6) \cdot 6x = 6x(x+6) \).
Use this LCD for adding, subtracting, or comparing these rational expressions within the same equation or in operations. Ensure to multiply both numerator and denominator by any missing factors when transforming each fraction to have this common denominator.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff69244f0-219a-466c-a858-e8fcb0f56c1f%2F5e004de6-3d20-413b-a31b-e3b2668ad3ee%2Fas35m_processed.jpeg&w=3840&q=75)
