Step-by-step explanation:
Is (a - b)² the same as (b - a)² ?
all the answers here have already discussed it,
here is my look at it
in general you need to define what a and b are that is whether they are positive no.s or negative
in case they are positive the result is same as you can take example any two positive numbers
a=4 and b=7
a-b would be 4–7
and that would be a negative of three (-3)
now you can square it i.e. multiply it two times (-3)*(-3)
it becomes +9
also b-a would be 3 whose square would also be 9
this was when both a and b were positive however the main thing is keeping signs common
