Which of the following binomials is a factor of x cubed plus 4 x squared plus x minus 6? a. x minus 2 b. x plus 2 c. x minus 4 d. x plus 4

The first thing we are going to do in this case is to rewrite the expression.
 We have then:
 x ^ 3 + 4x ^ 2 + x - 6
 Factoring the expression we have:
 (x-1) * (x + 2) * (x + 3)
 Therefore, we observe that the following binomial is a common factor:
 (x + 2)
 
 B. x plus 2
