Answer 2

Answer:

4 − 1

Step-by-step explanation:

( − 1 ) ( + 1 ) ( 2 + 1 )

( 2+ 1 ) ( + 1 ) − 1 ( 2 + 1 ) ( + 1 )

( + 1 ) 3 + ( + 1 ) − 1 ( 2 + 1 ) ( +1 )

4+13+(+1)−1(2+1)(+1)

4+3+(+1)−1(2+1)(+1)

4+3+2+−1(2+1)(+1)

4+3+2+−((+1)2+1(+1))

4+3+2+−(3+12+1(+1))

4 + 3 + 2 + − 3 − 2 − − 1

4 + 2 + − 2 − − 1

4+−−1

4 − 1
