full process of this question​

Answer 1

Answer:

(12-10)².

It is in the form of (a-b)²=a²-2ab+b² where a=12 & b=10.

(12-10)²=(12)²-2(12)(10)+(10)².

=144-240+100.

=-96+100. (Because +×-=- & largest number is important).

=4. (Because -×+=- & largest number is important).

(or).

(12-10)²=(2)²=4.

I think this is your answer.
