ANSWER
A. x = 2, √11, -√11
EXPLANATION
To find the zeros of f, which is a 3rd-degree polynomial, we can try some common values to see if any of them is a zero: 1, 2, -1, -2. In this case 2 is a zero of the function:
Now we can reduce our polynomial by dividing it by the factor (x - 2) and obtain a 2nd-degree polynomial, whose zeros are easier to find:
So we can rewrite f(x) as:
To find the other two zeros we have to solve:
Add 22 to both sides of the equation:
Divide both sides by 2:
And take square root. Remember that the square root has a positive and a negative result:
So the other two zeros are √11 and -√11.
The three real zeros of f are 2, √11 and -√11
