Question

(i) Check whether -3 and 3 are the zeroes of the polynomial x? – 9.​

Answer 1

Answer:

-3 and 3 are zeros of the polynomial x^2-9

Step-by-step explanation:

Let x^2-9=0

x^2=9

By taking roots on both sides,

x=-3, +3

Answer 2

X^2 -9
= (X -3)(X+3)
( by a^2 - b^2 simplification)

So
X = -3, +3
