Factor x^2-144

Problem

x2−144

Solution

1. Identify the expression as a difference of two squares, which follows the general form a2−b2

2. Determine the values of a and b by taking the square root of each term.

3. Calculate the square root of the first term: √(,x2)=x

4. Calculate the square root of the second term: √(,144)=12

5. Apply the formula for the difference of squares, a2−b2=(a−b)*(a+b) using a=x and b=12

Final Answer

x2−144=(x−12)*(x+12)
