Question

Check whether -3 and 3 are the zeroes of the polynomial
p(x) = x+3​

Answer 1

Answer:

p(-3)= -3+3

= 0

therefore -3 is a zero

p(3)= 3+3

=6

therefore 3 is not a zero

Answer 2

Answer:

-3 is a zero but 3 is not a zero!

Step-by-step explanation:

p(-3)= -3+3=0

p(3)= 3+3=6

so it's clear that -3 is a zero but 3 isn't.
