Question

find the 0 of the polynomial numbers​

Answer 1

Answer:

-2, +4

Step-by-step explanation:

First we equate polynomial to zero we get

x² - 2x - 8 = 0

x² -4x + 2x - 8 = 0

x(x - 4) + 2(x - 4) = 0

(x + 2)(x - 4) = 0

Since (x + 2)(x - 4) can be zero when either x = -2 or x= 4

∴ x = -2, +4
