Expand a product term which has sums with variables as factors.
A product term whose factors are a product or number and a sum has to be expanded. The term may contain up to three variables.
The shape of the term to be expanded may be one of these:
The term can be chosen to be
- one of group a, which means both factors are sum terms.
- one of groups a,b or c, which means at most one factor is a difference term.
- any of gropups a-d, which means both factors can be difference terms
- one of groups b,c or d, which means at least one factor is a difference term.
- squares can be disallowed, which means a variable will appear only in one of the factor terms.
- it can be specified that one of the variables in each factor may be a number.
The range for the numbers can be chosen.
The number of problems is selectable. The first problem can be presented with the answer in the form of a sample problem. If required, some space will be left so that the answer may be written on the sheet.
