Option (b) [tex](x-2)[/tex] is the correct answer.
A polynomial is an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).
So, [tex](x+2)*(x-2)[/tex]
[tex]=x^{2} -2x+2x-4[/tex]
[tex]=x^{2} -4[/tex]
Therefore, LHS is equal to RHS.
Hence, [tex](x-2)[/tex] is the polynomial that should be filled in that place.
