The FOIL method is a useful way to recall how to expand the product of two binomials (a + b) x (c + d). Multiply the First F terms, Outer terms, Inner terms, and the Last terms of the binomials, and sum the four products to obtain the formula (a + b) x (c + d) = ac + ad + bc + bd. Explain how the rectangular area diagram shown to the right justifies the FOIL The area of L is bd. b I The total area of the large rectangle is equal to the sum of the areas of F+0+1+L. Add the areas found from the previous steps. A=O
