This week in math 10 we learned about multiplying polynomials, distributive property, and the acronym FOIL.
The acronym FOIL stands for First terms, Outside terms, Inside terms, and Last terms. This is in regards to which terms you multiply and in what order, before you combine like terms.
Distributive property (FOIL) with binomials would look like: (a+b) (c+d) = ac + ad + bc + bd.
Example: In this expression, you begin by multiplying 3x and 2x, the FIRST terms, then 3x and 5, the OUTISDE terms, then 2 and 2x, the INSIDE terms, and finally 2 and 5, the LAST terms.
