Final answer:
The borrowing method is used in the context of algebraic expressions. It is a technique used to factor trinomials by rearranging terms and factoring.
Step-by-step explanation:
The borrowing method is used in the context of algebraic expressions. It is a technique used to factor trinomials, which are algebraic expressions with three terms. When factoring trinomials using the borrowing method, we look for pairs of numbers that multiply to give the constant term and add to give the coefficient of the middle term. By rearranging the terms and factoring, we can simplify the expression.
