Reply:It's an example of multiplying polynomials. In this case, they are polynomials of length 2, or binomials. Most people learn this as "FOIL", because that's easy to remember. For longer polynomials that you're multiplying, take one term from each grouped set of terms. Multiply these terms together. Repeat, being sure to choose a different combination of terms. Once you've done all possible choosings, add up all the terms you got from multiplying.
Reply:that is an example of a foil or more commonly, distributive property
Reply:This is clear example of the FOIL METHOD.





FOIL:





F = product of first terms





O = product of outer terms





I = product of inner terms





L = product of last terms
