Which of the following is a correct representation of the polynomial F(x)=x^4-5x^2+4 as a product of linear factors

C

Step-by-step explanation:

how to find the correct one?

just see on the x² constant number. it's -5 so

from ABCD the only option give -5 is C

A. (-2)(-2) + (-1)(-1) = 5

B. (-2)(-2) + (1)(1) = 5

C. (2)(-2) + (-1)(1) = -5

D. (-2)(2) + (-1)(-1) = -3

the one on the bottom left

step-by-step explanation:

all of the other ones have a specific pattern
