anonymous · Answer

hi sammy, are you still there?  And if so, do you still need help?

anonymous · Answer

yes please

anonymous · Answer

please, if i mention a term with which you are not familiar or a process that needs clarification, tell me and i will explain.  this is one of those special products they talk about when you are FOILing. It leads to a difference of two squares.

anonymous · Answer

for instance, if i have (x-2)(x+2), then i could FOIL this and get the answer of x^2-4

anonymous · Answer

notice above that the only difference between the binomials (the x-2 term and x+2 term) is the minus sign.

anonymous · Answer

whenever you have such a case, your product is simply the difference between the square of the first term and the square of the second term.  in the case of the example i gave you, the square of the first term is x^2 and the square of the second term is 4.
