Use the Factor Theorem to decide whether the given binomial of the form x - c is a factor of the polynomial given as P(x) If it is not, give the remainder when P(X) i divided by x - c
 9. 3x - 1 3x ^ 4 - 7x ^ 3 + x - 2

To solve this problem using the **Factor Theorem**, follow these steps:

1. The **Factor Theorem** states that if \( P(x) \) is a polynomial and \( x - c \) is a factor of \( P(x) \), then \( P(c) = 0 \). In other words, if the remainder when dividing \( P(x) \) by \( x - c \) is zero, then \( x - c \) is a factor.

2. Here, the binomial is \( 3x - 1 \). First, rewrite this binomial in the form \( x - c \):
   \[
   3x - 1 = 0 \implies x = \frac{1}{3}.
   \]
   So, we need to check if \( P\left(\frac{1}{3}\right) = 0 \).

3. The polynomial is \( P(x) = 3x^4 - 7x^3 + x - 2 \).

4. Now, substitute \( x = \frac{1}{3} \) into \( P(x) \):
   \[
   P\left(\frac{1}{3}\right) = 3\left(\frac{1}{3}\right)^4 - 7\left(\frac{1}{3}\right)^3 + \left(\frac{1}{3}\right) - 2.
   \]

Let's calculate the value of \( P\left(\frac{1}{3}\right) \).After calculating \( P\left(\frac{1}{3}\right) \), we get approximately -1.89. 

Since \( P\left(\frac{1}{3}\right) \neq 0 \), this means that \( 3x - 1 \) is **not** a factor of the polynomial \( P(x) = 3x^4 - 7x^3 + x - 2 \).

The remainder when dividing \( P(x) \) by \( 3x - 1 \) is approximately **-1.89**.
