>How can I introduce the basic concept of using the Foil Method to teach >multiplying of polynomials? Hi Angela, I usually attach it to distributive property.... (a + b) (c + d) 1) distribute the a through the c and d (ac + ad) 2) next distribute the b through the c and d (bc + bd) 3) add the answers together... (ac + ad + bc + bd) 4) this gives you FOIL.... This is a good method because it will make your discussion about how to multiply a problem like (a + b) (c + d + e) much easier... 1) ac + ad + ae 2) bc + bd + be 3) ac + ad + ae + bc + bd + be -Tom, for the T2T service |
