To factor the difference of squares, use the formula ( a^2 - b^2 = (a - b)(a + b) ). Identify ( a ) and ( b ) as the square roots of the two terms in the expression. For example, to factor ( 9x^2 - 16 ), recognize ( 9x^2 ) as ( (3x)^2 ) and ( 16 ) as ( 4^2 ), then apply the formula to get ( (3x - 4)(3x + 4) ).
