Question
**Implicit Differentiation Exercise**

**Objective:**
Find \(\frac{dy}{dx}\) by implicit differentiation.

**Given Equation:**
\[ 8x^2 - 13xy + 5y^2 = 32 \]

**Instructions:**

1. Differentiate both sides of the equation with respect to \(x\).
2. Use the chain rule and the product rule where necessary.

**Steps:**

1. **Write the results of differentiating with respect to \(x\):**

   The problem requires you to find the derivative of each term. Use:
   - The product rule for the term \(-13xy\).
   - The chain rule for the term \(5y^2\), treating \(y\) as a function of \(x\).

   \[ \frac{d}{dx} (8x^2) - \frac{d}{dx} (13xy) + \frac{d}{dx} (5y^2) = 0 \]

2. **Complete the differentiation:**

   \[
   16x - (13y + 13x\frac{dy}{dx}) + 10y\frac{dy}{dx} = 0
   \]

3. **Find \(\frac{dy}{dx}\):**

   Solve the equation for \(\frac{dy}{dx}\):
   \[
   \frac{dy}{dx} = \boxed{}
   \]

**Note:**

Fill in the details in the box provided on the answer sheet. This exercise involves algebraic manipulation to isolate \(\frac{dy}{dx}\) and express it in terms of \(x\) and \(y\).
