Multiply (x+3)(x-3)

Problem

(x+3)*(x−3)

Solution

1. Identify the pattern as a product of a sum and a difference, which follows the form (a+b)*(a−b)

2. Apply the formula for the difference of squares, which states that (a+b)*(a−b)=a2−b2

3. Substitute a=x and b=3 into the formula.

4. Simplify the expression by calculating the square of 3.

Final Answer

(x+3)*(x−3)=x2−9
