The (a - b)2 formula says (a - b) 2 = a 2 - 2ab + b 2. It is used to find the square of a binomial. This a minus b whole square formula is one of the commonly used algebraic identities. This formula is also known as the formula for the square of the difference between two terms.
The (a + b) whole square formula is the result of the square of the sum of two terms a and b. The (a + b) 2 formula is widely used to factorize the trinomials of the form a 2 + 2ab + b 2. This formula is explained below along with solved examples in the following section.
(a – b) 2 and (a + b) 2 are the basic algebraic identities used in the simplification of numerical expressions as well as binomial expressions with variables. In this article, you will understand the a minus b whole square formula and a plus whole formula along with proof and examples in detail.
Algebra Formulas. Algebra is a branch of mathematics that substitutes letters for numbers. An algebraic equation depicts a scale, what is done on one side of the scale with a number is also done to either side of the scale. The numbers are constants.

The a − b whole square identity is mainly used in two different cases in mathematics. Expansion. ( a − b) 2 = a 2 + b 2 − 2 a b. Simplification. a 2 + b 2 − 2 a b = ( a − b) 2. Examples. Let us learn how to use the formula of a minus b whole square from the following simple examples. ( 1) Expand ( 2 x − 5 y) 2.
The a square minus b square is used to find the difference between the two squares without actually calculating the squares. It is one of the algebraic identities. It is used to factorize the binomials of squares. What is a^2-b^2 Formula? The a 2 - b 2 formula is given as: a2 - b2 = (a - b) (a + b).
Special Binomial Products. See what happens when we multiply some binomials ... Binomial. A binomial is a polynomial with two terms. example of a binomial. Product means the result we get after multiplying. In Algebra xy means x multiplied by y. And (a+b) (a−b) means (a+b) multiplied by (a−b). We use that a lot here! Special Binomial Products.
Assume that $$(a-b)^2, (a^2+b^2)$$ and $$(a+b)^2$$ are in AP. So, difference between two consecutive terms will be same. $$(a^2+b^2)-(a-b)^2=(a+b)^2-(a^2+b^2)$$
Binomial Theorem. A binomial is a polynomial with two terms. example of a binomial. What happens when we multiply a binomial by itself ... many times? Example: a+b. a+b is a binomial (the two terms are a and b) Let us multiply a+b by itself using Polynomial Multiplication : (a+b) (a+b) = a2 + 2ab + b2.
