RESPONSE -->

with the first expression. x-2/x+4 would be seperated from eachother. only 2 would be divided by x. so x would subract from 2/x then added to 4. the answer would be 5

with the second expression, the parenthesis shows that each expression is in a group. so x-2 would divide over x+4. the answer would be 0
