Question
#12 can you show me how to do this right? I’ve attached my work.
**Problem Statement:**

Find all horizontal and vertical asymptotes (if any). (If an answer does not exist, enter DNE.)

\[
s(x) = \frac{16x^2 + 1}{4x^2 + 2x - 6}
\]

**Answers Provided:**

- Vertical asymptote: \( x = 1 \) (smaller value) ❌
- Vertical asymptote: \( x = -\frac{6}{4} \) (larger value) ❌
- Horizontal asymptote: \( y = 16 \) ❌

**Note:**
The problem requires identifying the correct horizontal and vertical asymptotes of the given rational function. The incorrect answers are marked with red crosses (❌).

The incorrect answers are marked with red crosses (❌).
The problem presented is:

\[ s(x) = \frac{16x^2 + 1}{4x^2 + 2x - 6} \]

**Solution Steps:**

1. **Identify and Factor the Denominator:**
   - The task is to simplify the expression, starting by factoring the denominator: \( 4x^2 + 2x - 6 \).

2. **Factorization Steps:**
   - Decompose into simpler expressions using cross multiplication indications:
     - Write down the product \( ac = 24 \) (from \( a = 4, c = -6 \)).
     - Find the factors of 24 which sum up to \( b = 2 \). These are \(-4\) and \(6\).

3. **Intermediate Steps:**
   - Break the middle term using these factors:
     \[
     4x^2 - 4x + 6x - 6
     \]
   - Factor by grouping:
     \[
     4x(x-1) + 6(x-1)
     \]
   - Combine common factors:
     \[
     (x-1)(4x+6)
     \]

4. **Vertical Asymptote (VA) Identification:**
   - Set the denominator equal to zero to find the vertical asymptotes.
   - \( x - 1 = 0 \) results in a vertical asymptote at \( x = 1 \).

5. **Simplifying by Solving Remainder Equation:**
   - Solve the equation \( 4x + 6 = 0 \):
     \[
     4x = -6
     \]
   - Simplify to find:
     \[
     x = -\frac{6}{4} = -\frac{3}{2}
     \]

**Conclusion:**

The function has a vertical asymptote at \( x = 1 \). Further simplification might include reducing or canceling terms, if possible, depending on the form of \( s(x) \).
