Find each sum. (3n2 – 5n + 6) + (–8n2 – 3n – 2) = –11n2 – 8n – 4 –11n2 – 2n + 4 –5n2 – 8n + 4 –5n2 – 2n – 4

-5n² - 8n + 4

Step-by-step explanation:

Given the expression

(3n²– 5n + 6) + (–8n²– 3n – 2)

Expand the bracket

3n²– 5n + 6 –8n²– 3n – 2

Collect the like terms

3n²-8n²-5n– 3n – 2+6

-5n² - 8n + 4

This gives the required result

mean, 40.6
