Simplify (x-2)(x+2)

Problem

(x−2)*(x+2)

Solution

1. Identify the expression as a product of a sum and a difference, which follows the difference of squares pattern (a−b)*(a+b)=a2−b2

2. Apply the formula by setting a=x and b=2

3. Square the individual terms to get x2 and 2

4. Simplify the constant term 2 to 4

Final Answer

(x−2)*(x+2)=x2−4
