Question

x²-2x-8


Find zeroes of this polynomial and verify the relationship between zeros and coefficients.

Answer 1

Explanation:

x² - 2x - 8 = 0

x² -4x +2x -8 = 0

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

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

then (x - 4 ) = 0

x = + 4

x = 4

and (x + 2 ) = 0

x = - 2

values of x are " 4 " and " -2 "
