Question

Using synthetic subtitution determine if the viven binomial: (×-2) and (×+1) are factors of the polynomial p(×)=4x^4−21x^3+18x^2⋅19x−6

Answer 1

2 | 4 -21 18 -19 -6
8 -26 -16 -70
---------------------------------
4 -13 -8 -35 -76

(x-2) is not a factor

-1 | 4 -21 18 -19 -6
-1 22 -40 59
__________________________

4 -22 40 -59 53


x+1 is not a factor
