Answer:

2nd, 4th and 5th

Step-by-step explanation:

remember :

+- = -

-+ = -

-- = +

++ = +

so, the first option has all signs of all terms as +. that is wrong, as we have -1 1/5

also the third option turns all signs to +. and is therefore wrong.

the second option makes the signs +, + and -. that is correct (like the original expression). as +- = -

the fourth option is just removing the brackets, which did not change anything about the signs, as there was a + in front of the original brackets. so, it is still the correct +, + and -.

the fifth option has the first two terms with -- signs, which makes them both +.

and the third one is +-, so it is -.

so, we end up again with the correct +, + and - signs.
