Question

x square -2x-8
find the zeros of the following quadratic polynomial.

Answer 1

xx-2x-8 = 0
xx-2x = 8
xx= 8-2x
x= √ 8-2x

Answer 2

Heya !!




X² - 2X - 8



X² - 4X + 2X - 8


X ( X - 4 ) + 2 ( X - 4 )




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



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



X = 4 or X = -2.


Hence,


4 and -2 are the two zeroes of the given quadratic polynomial X² - 2x - 8.
