Question
### Finding Complex Zeros of a Polynomial Function

**Problem Statement:**
Find the complex zeros of the following polynomial function and write \( f \) in factored form.

\[ f(x) = x^4 + 4x^3 + 4x^2 + 36x - 45 \]

---

**Steps:**

1. **Finding the Complex Zeros:**

To find the complex zeros of \( f(x) \), we need to solve the equation:

\[ x^4 + 4x^3 + 4x^2 + 36x - 45 = 0 \]

(Simplify your answer. Type an exact answer, using radicals and \( i \) as needed. Use integers or fractions for any numbers in the expression. Use a comma to separate answers as needed.)

**Answer Box:**
\[ \text{The complex zeros of } f \text{ are } \_\_\_\_\_\_. \]

---

2. **Factoring the Polynomial:**

Next, use the complex zeros to factor \( f \).

**Answer Box:**
\[ f(x) = \_\_\_\_\_\_ \]

(Type your answer in factored form. Type an exact answer, using radicals and \( i \) as needed. Use integers or fractions for any numbers in the expression.)

---

**Final Instruction:**

Enter your answer in each of the answer boxes provided.
