Question

check whether -3 and 3 are 0 of the polynomial x^2-9​

Answer 1

Answer:

note ; the zeros of a polynomial is that value variable ( here the variable is x)

at which,. the polynomial becomes zero.

here ,we have to check whether x=-3 and x=3 ,are zeros of polynomial or not.

let ,the polynomial be p(x), then,

p(x)= x2-9

now , let's put x=-3 and x=3 one- by-on

in p(x) and see whether the p(x ) becomes zero or not.

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

=9-9

=0

p(3)=3^2-9

=9-9

=0

here , we can see ,the polynomial becomes zero at x=3 and x= -3.

thus ,we can say that, 3 and -3 are the zeros of the given polynomial p(x)=x^2-9.
