Put the values of a and b in the expression.
(-9 - 9)^2 = (-18)^2 = 324
Hope this helps.

Since a=-9 and b=9,
(a-b)2 =(-9-9)2
=(-18)2
=324

a - b = -9 - 9 = - 18
So, (a - b)^2 = (- 18)^2 = 324
If you meant (a - b)2, it will be - 36

(a - b)2
= 2[(-9)-(9)]
= 2[-18]
= -36
If it was a typo and you meant (a-b)², then
(a-b)²
= [(-9)-(9)]²
= [-18]²
= 324
