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

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

you just switch the numbers basically so it would be 3/17
