(a-b)^n Formula Expander

(a-b)^n Formula Expander is a tiny web based tool used to expand the formula based on the given n value. The n is the power of (a-b). For example, the value of n is 2 then the expression (a-b)^2 = a^2-2ab-b^2. This formula expander can be used to find the expression of (a-b)^2, (a-b)^3, (a-b)^4 up to (a-b)^n. Provide the n value in the given text box and hit calculate button provides the respective expression. Refer the below table for example input & output of (A-B)n calculator
