Question

Find the zeroes of x²-2x-8 and findthe relationship between its zeroes.​

Answer 1

X=2.330746 IS ZERO OF THE POLYNOMIAL  

Answer 2

Answer:

x²+2x-4x-8

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

(x-4) (x+2)

Alpha = 4

beta = -2

relationship between its zeroes.

alpha+beta = -b\a

4 - 2 = -(-2)\1

2=2

alpha×beta = c\a

4 × - 2 = -8\1

-8 = -8

hence proved
