Question

find the zeros of the following quadratic polynomial and verify the relationship between the zeros and the coefficient x square - 2 x minus 8​

Answer 1

Answer:

Step-by-step explanation:

x^2 - 2x - 8

x^2 - 4x + 2x - 8

x (x - 4) + 2 (x - 4)

(x + 2) (x - 4)

x = -2 , 4

alpha = -2 , beta = 4

a = 1 , b = -2 , c = -8

relationship :

sum of zeros = -b / a

-2 + 4 = -(-2) / 1

2 = 2

product of zeros = c / a

-2 × 4 = -8 / 1

-8 = -8
