Step-by-step explanation:
Answer:
0
Step-by-step explanation:
2a(b−c)+b(2c−2a)+4c(0.5a−0.5b)
To simplify this we need to remove the parenthesis
Distribute 2a, b and 4c inside the parenthesis
2ab -2ac + 2bc - 2ab + 2ac - 2bc
now we combine like terms'
2ab - 2ab becomes 0
-2ac +2ac becomes 0
+2bc - 2bc becomes 0
So final answer is 0
