Question 1154817: Use factor theorem ad synthetic division to determine which if the following is/are a factor of:
x^3 − 2x^2 + 3x − 6
A) x − 2 B) x + 1 C) x − 1 D) x + 2 Answer by ikleyn(52781) (Show Source):
I will use the grouping method
x^3 - 2x^2 + 3x - 6 = (x^3 - 2x^2) + (3x - 6) = x^2*(x-2) + 3*(x-2) = (x-2)*(x^2+3).
The factors are (x-2) and (x^2+3).
One of them is from your list.
