# A + 2ab + b

Let the literals a and b represent two terms in algebraic form. The subtraction of b from a is written as a − b. It is basically an algebraic expression and also a binomial. The square of this expression is written as (a − b) 2 in mathematical form and it is expanded as a 2 − 2 a b + b 2 mathematically.

Thus we can use any method we have at our disposal to Mar 04, 2018 = a 2 - 2ab + b 2 Rearrange the terms and we get: = a 2 + b 2 - 2ab Hence, in this way we obtain the identity i.e. (a - b) 2 = a 2 + b 2 - 2ab Following are few applications this identity. Example 1: Solve (3a - 2b) 2 Solution: This proceeds as: Given polynomial (3a - 2b) 2 represents identity second i.e. (a - b) 2 Oct 08, 2020 The only appropriate response I can think of is how to interpret the exponent. Any parentheses raised to the nth power means you have to re-write that expression n times and then multiply them all. In this case the exponent is just 2, so we re-wri In mathematics, factorization (or factorisation, see English spelling differences) or factoring consists of writing a number or another mathematical object as a product of several factors, usually smaller or simpler objects of the same kind.For example, 3 × 5 is a factorization of the integer 15, and (x – 2)(x + 2) is a factorization of the polynomial x 2 – 4.

Learning Outcome The identity (a+b) 2 = a 2 + 2ab + b 2 is verified by cutting and pasting of paper. This identity can be verified geometrically by taking other values of a and b. Activity Time (a+b)²-(a-b)² Here, we Have (a+b) ² -(a-b) ² We have equation for(a+b)² = a² + 2ab + b² We have equation for(a-b)² = a² - 2ab + b² So we can use it and we write below step (a² + 2ab + b² )-( a² - 2ab + b² ) After open the brackets we got, a² + 2ab + b² - a² +2ab - b² 2ab+2ab =4ab. keep smiling ️ Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.
