Question

Write all formulas of algebraic identities in chart paper, Activity:- Verify the algebraic identity (a-b)2 = a2 + b2 - 2ab

​

Answer 1

ATTACHMENT ABOVE IS ABOUT THE BASIC ALGEBRAIC IDENTITIES

ACTIVITY:

$to \: prove \: {(a - b)}^{2} = {a}^{2} + {b}^{2} - 2ab \\ >{(a - b)}^{2} = (a - b)(a - b) \\ = {a}^{2} - ab - ba + {b}^{2} \\ = {a}^{2} - 2ab + {b}^{2} \\ = {a}^{2} + {b}^{2} - 2ab \\ hence \: proved$
