Answer:
[tex]z^2-144[/tex]
Step-by-step explanation:
Here the given expression,
[tex](z-12)(z+12)[/tex]
∵ By using the algebraic property,
[tex](a+b)(a-b)=a^2-b^2[/tex]
We get,
[tex](z-12)(z+12)=(z)^2 - (12)^2[/tex]
[tex]\implies (z-12)(z+12)=z^2-144[/tex]
Which is the required product.
Therefore, FIRST option is correct.
