Which is equivalent to (x + 12) (x - 12) ?

x + 24x - 144

x² - 144

x + 144

x - 24x - 144

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
