Interactive tutorial with examples and many practice problems on how to multiply two binomials using the FOIL method. $$ (-2 x-3)(3-x) $$ Jonathan B. Tufts University. Without FOIL, when multiplying polynomials we use different methods such as area models. Jump to Question. Youâve been âFOILâed if you believed for one second Iâve changed my stance on teaching the FOIL method on my classroom. Since there are no like terms to add together, you're done.If you're dealing with negative numbers or subtraction, you have to watch the signs.For example, if the problem is -3x(4x+2y), you'll have to multiply negative 3x times everything in the parenthesis.
