It's hard to be sure that I definitely understand the question.
Let's see if this helps:
(122) = 144, so -(122) = -144
(-122) = 144, so -(-122) = -144
(-1)2=1 all squared numbers turn out positive and 12=1 (-1)2=1 all squared numbers turn out positive and 12=1
-12 squared is 144.
12 squared is equal to 144. This is because 12 squared means 12 multiplied by itself, which is 12 x 12 = 144.
12 squared plus 18 squared is equal to 468.
12 squared (12 x 12) = 144
7
144.
when 144 is squared it is the same as 12
the answer is either 42 36 58 12 5 6 90 45 18
12 squared (12 x 12) = 144
132
122 + 52 = 169 This is equal to 132.
