Use FOIL to multiply. (x + 2)(x – 2)
Product of sum and difference of same two terms (A + B)(A – B) = A2 – B2 Square of the first minus square of the second
Multiply. (r + 2)(r – 2)
Multiply. (2x + 3)(2x – 3)
Multiply. (2x3 + y)(2x3 – y)
Multiply. (y6 – y2)(y6+ y2)
Squaring a Binomial Multiply the binomial by itself
