Question

3. Which of the following binomials is a factor of x³+4x²+x-6?

O x-2
O x + 2
O x-4
O x + 4

Answer 1

It is x+2

Explanation:

For the first option, x-2, use synthetic division to solve. Since it has a remainder (20/x-2), this is not the correct option. For the second solution, x+2, we can also use synthetic division. When you write it out, you can see that there is no remainder. Therefore, your answer is x+2.
