if x-2 is a factor of x- bx + b, where b is a
constant, what is the value of b ?

Step-by-step explanation:

You know that a factor of the given polynomial is:

Then, in order to find the value of "b", which is a constant of the polynomial, you need to follow these steps:

1. You must rewrite the polynomial as:

2. Now you must substitute into the polynomial:

3. Since 2 is a zero of the polynomial, you can substitute :

4. Finally, you must solve for the constant "b" to find its value. Then, this is:
