Question

what is the zeroes of x2-2x-8

Answer 1

Hiii friend,

X²-2X-8

=> X²-4X+2X-8

=> X(X-4)+2(X-4)

=> (X-4)(X+2)

=> (X-4) = 0 OR (X+2) = 0

= X = 4 or X = -2

Hence,

4 and -2 are the zeros of the polynomial X²-2X-8.

HOPE IT WILL HELP YOU..... :-)

Answer 2

x^2 - 2x -8 = 0
(x + 2)(x - 4) = 0
x + 2 = 0 → x = -2
x - 4 = 0 → x = 4
