Question

(ii) Check whether -3 and 3 are the zeroes of the polynomial x^2-9​

Answer 1

Answer:

_________________

Put the value of zeros in given polynomial :

p ( x ) = x^2 - 9

where x is zero .

_________________

( i ) p ( -3 ) = -3^2 - 9

= 9 - 9

= 0

( ii ) p ( 3 ) = 3^2 - 9

= 9 - 9

= 0

Hence , it checked & both of the number ( -3 , 3 ) are the zeroes of the polynomial x^2 - 9 .
