Question

Find
the zenes of the Quadratic Polynomial
x² - 2x-8​

Answer 1

AnsWer:-

Given Polynomial:- x² - 2x -8

x²- 4x + 2x - 8

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

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

x + 2 = 0 or x - 2= 0

x = -2 or x = 2

Answer 2

Answer:

By middle term spilting

x^2-2x-8

x^2-(4-2)x-8

x^2-4x+2x-8

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

(x-4)(x+2)

there are two zero of this polynomial

x=4

x=-2
