Apply binomic formula expansion rules to simplify term.

Apply the well known binomic formula expansion rules to expand and simplify terms. The summands of the formula's factors will be either a variable and a literal number or both of them will be variables. In no case, both summands will be numbers, which means the expanded term will always contain variables and it does not simplify to a single literal number. The number of problems is selectable. For the types of formulas that will appear it can be specified that only some of the three binomic formulas will be used. Variables that appear will always be named a and b or x and y.
