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. In mathematics, this algebraic identity is used as a formula and it is called in the following three ways. (a-b)²=

Solution: We know, (a + b)2 = a2 + b2 + 2ab Factor the first three terms and keep bringing the -4 down to the next line: a - 2ab+b - 4 Factor the a -2ab+b first as (a-b)(a-b) and then shorten that to 1. Using the identity (a + b)+2ab+ b2, derive the formula for (a + b+ep. Hence, find the value of (2x - 3y + 4z)2.
