Question

check weather -2 and 2 are zeros of the polynomial x +2

Answer 1

Given:

To check whether -2 and 2 are the zeroes of x+2.

To Check :

Whether 2 & -2 are the zeroes of x-2.

Answer:

Given polynomial = x+2 = p(x) (say)

So,

p(2) = 2+2 =4 .

Hence on putting 2 in p(x) it is not coming 0 .

So, 2 is not a zero of x-2 .

p(-2) = (-2)+2 =2-2 =0.

Hence on putting -2 in p(x) it is coming 0 .

So, 2 is a zero of x-2 .
