Answer:
Sum is - 5n² -8n + 4.
Step-by-step explanation:
Given : (3n² – 5n + 6) + (–8n²– 3n – 2) .
To find : Sum .
Solution : We have (3n² – 5n + 6) + (–8n²– 3n – 2) .
Combine like terms :
(3n² - 8n²– 5n - 3n + 6 - 2).
- 5n² -8n + 4.
Therefore, Sum is - 5n² -8n + 4.
Use a calculator it's not hard
Answer:
Step-by-step explanation:
-(-2 + 3x - 1/2) = -( -2 - 0.5 + 3x)

= -1*(-2.5) + (-1)*3x
= 2.5 - 3x
2.5 - 3x is not equivalent to 2.5 + 3x
