Given the function f(x) as follows:
The function has a root at x = 3
We will use the synthetic division to find the other roots:
We will divide the coefficients by 3
As follows:
So, the given function will be written as follows:
Factor the term of the quadratic function
So, there are three zeros x = 1, 2, 3
So, the answer will be option 4) x = 1, x = 2
