The perfect square rule is a technique used to expand expressions that are the sum or difference of two squares, such as (a + b)^2 or (a - b)^2. The rule states that the square of the sum (or difference) of two terms is equal to the sum (or difference) of the squares of the terms plus twice the product of the terms.

Refer the below table for example input & output of (A+B) n and (A-B) n calculator. (A+B)^n and (A-B)^n formula expander to perform formula expansion for any n value or nth power of (A+B).
According to the theorem, it is possible to expand the polynomial (x + y) n into a sum involving terms of the form ax b y c, where the exponents b and c are nonnegative integers with b + c = n, and the coefficient a of each term is a specific positive integer depending on n and b.
The binomial theorem formula is used in the expansion of any power of a binomial in the form of a series. The binomial theorem formula is (a+b) n = ∑ n r=0 n C r a n-r b r, where n is a positive integer and a, b are real numbers, and 0 < r ≤ n.
The binomial theorem is an algebraic method for expanding any binomial of the form (a+b) n without the need to expand all n brackets individually. The binomial theorem formula states that . A binomial contains exactly two terms.
