Hello, i need help Performing  the indicated operation in the image below and state for which values the final expression is undefined (if any)

**Title: Operations on Rational Expressions**

In this exercise, you are asked to perform the indicated operations on the given rational expressions and determine for which values the final expression is undefined (if any).

**Problems:**

1. **Problem 14:**
   \[
   \frac{x^2 + 10x + 24}{x^2 + 13x + 36} \cdot \frac{x^2 + 9x}{x^2 + 13x + 42}
   \]

   *Steps to Solve:*
   - Factor the polynomials in the numerators and denominators.
   - Perform the multiplication of the fractions.
   - Identify any values of \(x\) that make the denominator zero, rendering the expression undefined.

2. **Problem 15:**
   \[
   \frac{x^2 - 4x + xy - 4y}{10x^2 - 10y^2} \div \frac{x - 4}{6x - 6y}
   \]

   *Steps to Solve:*
   - Convert the division into multiplication by taking the reciprocal of the second fraction.
   - Factor the polynomials in the numerators and denominators.
   - Perform the multiplication of the fractions.
   - Determine which values of \(x\) or \(y\) make the denominator zero, making the expression undefined.

For these problems, consider simplifying the factored expressions and cancel out common terms where applicable. Always remember that a rational expression is undefined wherever its denominator equals zero.
