WebThe (a + b) 2 formula is the algebraic identity used to find the square of the sum of two numbers. i.e., it is used to find the square of a binomial a + b. The formula of (a+b) whole square says (a + b)2 = a2 + 2ab + b2. To prove this formula, we will just multiply (a + b (a + b).

WebThe special product of the binomials a + b and a − b is equal to the difference of squares of the terms a and b. ∴ ( a + b) ( a − b) = a 2 − b 2. The mathematical equation expresses that the product of sum and difference basis binomials, which contain the same terms is equal to the difference of them. It is used as a formula in mathematics.
