Determine whether each binomial is a factor of x^3 + x^2 - 16x - 16.
42. x + 2
43. x - 4
44. x + 1
45. x - 1
46. x - 2
47. x + 4
If the binomial is a factor, then the root will be true
Example x+2 has the root x=-2 sub in -2 -8 +4 +32-16 does not equal 0 not a factor
example x+1 Has the root x = -1 sub in -1 -1+1+16-16 = 0 Is a factor
Can you do the others?
