The original expression evaluates to 54.4 as shown in the first working.
_____
For some reason, 3.4 got transcribed to be 1.7 in the 3rd line of the second working. There is no math operation in the expression that requires 3.4 to be divided by 2.
You put it over it’s number place so since .5 is in the tenths place you put it over 10
So it would be 2 5/10 after simplifying you get 2 1/2
( − 5 ) ( + 5 ) ( 2 + 2 5 )
