![**Polynomial Division Instructions**
Two polynomials \( P \) and \( D \) are given. Use either synthetic or long division to divide \( P(x) \) by \( D(x) \), and express \( P \) in the form \( P(x) = D(x) \cdot Q(x) + R(x) \).
\[ P(x) = x^4 + 3x^3 - 18x \]
\[ D(x) = x - 4 \]
**Division Box:**
\[ P(x) = \boxed{} \]
**Explanation:**
To find the quotient \( Q(x) \) and the remainder \( R(x) \), one must perform polynomial division. Start by using either synthetic division or long division:
1. **Synthetic Division**: Suitable for dividing by linear divisors.
- Use the root of \( D(x) = 0 \), which is \( x = 4 \), as the divisor.
- List the coefficients of \( P(x) \).
- Follow the synthetic division process, writing the final result in terms of quotient and remainder.
2. **Long Division**:
- Arrange \( P(x) \) and divide by \( D(x) \) using traditional long division.
- Continue dividing until the degree of the remaining polynomial is less than the degree of \( D(x) \).
- Express the result as a combination of quotient and remainder.
By performing these steps, you will express \( P(x) \) in the desired form.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa9130211-60c6-4202-a6c7-5cc4c0cfeca2%2F4fc3f247-01db-4e00-aaac-df66ba9c439e%2Fvib8si_processed.png&w=3840&q=75)
