Question

check whether-3 and 3 are the zeroes
of the polynomial x²-9​

Answer 1

Answer:

first we will take -3 as X and put the value in the polynomial we get (-3)²-9

=9-9

=0

and then we will take for 3 as x value and put into the polynomial then we get

=(3)²-9

=9-9

=0

then we can say that - 3 and 3 are the zeros of polynomial x² - 9

Answer 2

Answer:

put x, = -3

x²-9 = 0

-3²-9 =0

9-9=0

0=0

put x = 3

x² - 9 = 0

3² -9 = 0

9-9 =0

0=0

hence verified, -3,3 are the zeroes of polynomial x²-9
