Question

plzzz solveit it will be helpful for me​

Answer 1

Answer:

none of these...............

Answer 2

Answer:

(z+3)*(z-3)

using identity (a+b)*(a-b)=a²-b²

here z is' a' and 3 is 'b' so

(z+3) * (z-3)=z²-3²=z²-9

answer=z²-9 which does  not match any option so "none of these" is your answer.

hope it helps!
