One root of a third degree polynomial function f(x) is -5 + 2i. which statement describes the number and nature of all
roots for this function?
f(x) has two real roots and one complex root.
f(x) has two complex roots and one real root.
f(x) has three complex roots.
f(x) has three real roots.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

it would be a on edgenuit y
