Find lcd

Find the LCD of \( \frac{3}{x-2} \) and \( \frac{1}{x+3} \)

Solution

The image asks to find the LCD (Least Common Denominator) of two rational expressions:

3x2and1x+3\frac{3}{x - 2} \quad \text{and} \quad \frac{1}{x + 3}

Steps to Find the LCD:

  1. Identify the denominators:

    • The first denominator is x2x - 2.
    • The second denominator is x+3x + 3.
  2. Find the Least Common Denominator (LCD): Since the denominators are x2x - 2 and x+3x + 3, the least common denominator is simply the product of the two distinct factors.

Thus, the LCD is: (x2)(x+3)(x - 2)(x + 3)

This expression represents the least common denominator of the two rational expressions.
