    Option 2 is the correct option

    Step-by-step explanation:

    Step 1:

    Given expression : (x + 12) (x - 12)

    We need to find the expression from the given options which matches the given expression

    Step 2:

    The given expression is of the form (a+b) (a-b)

    where a = x and b = 12 here

    The product of this is given by formula

    (a+b) (a-b) = (a² - b²)

    Substituting the value of a and b in formula we get

    (x + 12) (x - 12) = x² - 12² = x² - 144

    Hence option 2 is the correct option from the given list.

    Step 3:

    Answer:

    Option 2 is the option which matches the given expression
