Factor a^2-b^2

Problem

a2−b2

Solution

1. Identify the expression as a difference of two squares, which follows the general form x2−y2

2. Apply the formula for factoring a difference of squares, which states that x2−y2=(x−y)*(x+y)

3. Substitute a for x and b for y into the formula to obtain the factored form.

Final Answer

a2−b2=(a−b)*(a+b)
