This week in math i have learned how to FOIL polynomials. Foiling is a method used to find the value of a polynomial. FOIL stands for: F – first term in each bracket, O – outside terms, I – inside terms and L – last term in each bracket. An example of a polynomial being foiled below.
after you do the multiplication part you must add or cancel out like terms. A like term is when two terms are alike, for example 8x and 8x are like terms, 8 and 8 are like terms 8 and 8x are not like terms. To cancel out like terms you add or subtract like terms depending if they are negative or positive.
