Hello Friend !
The answer is given below :
1) 9a² - 8ab - 2b² - ( 3a² - 4ab + 6b² )
⇒ 9a² - 8ab - 2b² - 3a² + 4ab - 6b²
⇒ 6a² - 4ab - 8b²
Dividing the complete equation by 2
⇒ 3a² - 2ab - 4b²
This is answer to first part of question.
2) a² + ab + c² - ( a² - d²)
⇒ a² + ab + c² - a² + d²
⇒ d² + c² + ab
This is answer to part 2 of the question !
Hope this helps !
