For item number 2
Answer:
8s² - 25s + 12
Step-by-step explanation:
(8s²- 4s + 10) - (21s -2)
First, Distrubute muna natin so,
(8s² - 4s + 10) - (21s - 2)
8s²- 4s + 10 - 21s + 2
Second, i-add muna
= 8s² - 4s + 10 - 21s + 2
= 8s² - 4s + 12 - 21s
Lastly, combine like terms
= 8s² - 4s + 12 - 21s
= 8s² - 25s + 12
