A term is given which is the expanded form of a binomic formula. The original binomic formula has to be found.

A term is presented. The term is the expanded form of one of the three binomic formulas. The task is to find the original binomic formula in the form of a product of two sums.

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.
