Math Problem Statement
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
Solution
To solve this problem using the Factor Theorem, follow these steps:
-
The Factor Theorem states that if is a polynomial and is a factor of , then . In other words, if the remainder when dividing by is zero, then is a factor.
-
Here, the binomial is . First, rewrite this binomial in the form : So, we need to check if .
-
The polynomial is .
-
Now, substitute into :
Let's calculate the value of .After calculating , we get approximately -1.89.
Since , this means that is not a factor of the polynomial .
The remainder when dividing by is approximately -1.89.
