Question

ab c ka whole square​

Answer 1

Answer:

To find :

(a-b-c)²

Solution :

(a - b - c )²

This can be split up as,

= ( a - b - c ) ( a - b - c )

Multiplying both the terms, we get,

= a ( a - b - c ) - b ( a - b - c ) - c ( a - b - c )

= a² - ab - ac - ab + b² + bc - ac + bc + c²

= a² + b² + c² - 2ab + 2bc - 2ac

Therefore,

( a - b - c )² = a² + b² + c² - 2ab + 2bc - 2ac
