Final answer:

The least common denominator (LCD) for the rational equation is
\((x+4)(x+2)(x-2)\).

Step-by-step explanation:

To find the least common denominator (LCD) for the rational equation
\((x)/(x+4) + (x-1)/(x+2) = (3)/(x^2+2x-8)\), we need to factor the denominators and identify the unique factors.

1. **Factorization of Denominators:**

-
\(x+4\) is already a linear factor.

-
\(x+2\) is already a linear factor.

- Factorizing
\(x^2+2x-8\), we get \((x+4)(x-2)\).

2. **Identify Unique Factors:**

- The unique factors are
\(x+4\), \(x+2\), and \(x-2\).

3. **Determine the LCD:**

- The LCD is the product of all unique factors raised to their highest powers.

- Therefore, the LCD is
\((x+4)(x+2)(x-2)\).

So, the LCD for the given rational equation is
\((x+4)(x+2)(x-2)\).
