pls say,this is from algebra,class 7th cbse​

Answer 1

Answer:

(A) is the correct answer to this question

Answer 2

Answer:

An additive inverse of a number is defined as the value, which on adding with the original number results in zero value. It is the value we add to a number to yield zero. Suppose, a is the original number, then its additive inverse will be minus of a i.e.,-a, such that a+(-a) = a – a = 0

so the answer is

1) -2a² + b² + 3ab - 6

(2a² - b² - 3ab + 6) + ( -2a² + b² + 3ab - 6 ) = 0
