Check whether -2 and 2 are the zeroes of the polynomial x4 - 16

2
yes
sotty
sorry
its ok it was my mistake
[tex] X^{4} =16 [/tex] ------------------1 ⇒[tex] X^{4}= ( +,- 2) ^{4} [/tex] ⇒X=-2 or X=+2 ⇒put the value of X in eq 1 ⇒when X=-2 then 16=16 ⇒when X=+2 then 16=16

 X^{4} =16 ------------------1
 X^{4}= ( +,- 2) ^{4}
 ⇒X=-2 or X=+2
 ⇒put the value of X in eq 1
 ⇒when X=-2 then 16=16
⇒when X=+2 then 16=16
