Answer:
(x-1) ( x -i) (x+i)
Step-by-step explanation:
x^3 -2x^2 +x-2
Factor by grouping
x^3 -2x^2 +x-2
x^2(x-2) +1(x-2)
Factor out (x-2)
(x-2) (x^2+1)
Rewriting
(x-1) ( x^2 - (-1)^2)
(x-1) ( x -i) (x+i)
Answer:
Step-by-step explanation:
Note that if you combine the two equations in this SYSTEM, you get the (true) equation 0 = 0. Thus, there are infinitely many solutions.
I think it’s B might be wrong though
