Factoring by grouping is a common method used in algebra to factor polynomials. This method involves grouping terms together in a specific way to simplify the expression and factor out common factors. It is a useful technique that can help make complex polynomials easier to work with.
When factoring by grouping, the key is to look for pairs of terms within the polynomial that have a common factor. By grouping these terms together, you can then factor out the common factor and simplify the expression. This method is particularly helpful when dealing with polynomials that have four or more terms.
