Simplify (x+3)(x-3)

Problem

(x+3)*(x−3)

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)=a^2−b^2

2. Apply the formula by setting a=x and b=3

3. Square the individual terms to get x^2 and 3^2

4. Simplify the constant term 3^2 to 9

Final Answer

(x+3)*(x−3)=x^2−9
