What is the complete factorization of the polynomial below
DerKrebs [107]

Answer:

a. \ (x-2)(x+i)(x-i)

Step-by-step explanation:

First of all let's notice that (x-i)(x-i)=(x-i)^2 = x^2+2xi-1 \in \mathbb{C} while our original polynomial is real. So we can rule out the even options B and D. At this point, if the polynomial has a factor of (x-\alpha) it means tha \alpha is a zero of the polynomial. Let's check both 2 (for option a) and -2 (for option c)

p(2)=2^3-2(2)^2+2-2= 8-8+2-2=0

p(-2)= (-2)^3-2(-2)^2+(-2)-2=-8-8-2-2=-20

At this point 2 is a zero, and our final factoring is a(x-2)(x+i)(x-i)
