X=7
Step 1: add nine to both sides it becomes
-2x=-23+9 —> -2x=-14
Step 2: divide by -2 on both sides it becomes
X=-14/-2 —> x=7
Answer:

Step-by-step explanation:
The zeros of the polynomial are all the values of x for which the function 
In this case we know that the zeros are:


, 
Now we can write the polynomial as a product of its factors

Note that the polynomial is of degree 3 because the greatest exponent of the variable x that results from multiplying the factors of f (x) is 3
