Question

Check whether -3 and 3 are the zeros of the polynomial x^-9


​

Answer 1

Answer:

Answer. yes they are. (-3)^2 - 9 = 0

Step-by-step explanation:

x²-9 = 0 , x² = 9, x = +√9, -√9 , x = +3, -3. Therefore , -3 and 3 are zeroes of the polynomial x²-9

OR

(-3)^2 - 9 = 0. also,

(3)^2 -9 = 0.

hence 3 and -3 are the zeroes of the polynomial (x)^2 - 9
