Sir your method is very simple it will cover all concept

[@mamtadevisah895]

but there is a mistake 😕 that in shortcut method the square of (-10) is 100 not -100 😄😄😄 but answer is write because if you multiply minus to minus u will get plus but u had stil written minus.
i think u have to practice more. Because practice make man perfect. 😁😁😁
