Which one’s are not correct and what did they do wrong

Answer:
Only LOKI is correct
Step-by-step explanation:
Elektra multiplied 8 with the inside parenthesis but it was wrong to do.
Green Goblin took 2x outside with negative sign but that is wrong
Morbius did the same mistake as Green Goblin at first step but then corrected it in the second step, still it's wrong
