​

Answer 1

Answer:

- 4y² +2y+ 5

Step-by-step explanation:

sum of 6+ 4y + y2 and 8-5y+3y

6+ 4y + y2 + 8-5y+3y

14 + 2y + y²

sum of 6y2 - 4y and - y2 + 4y +9

6y2 - 4y + (-y2 + 4y +9)

6y2 - 4y - y2 + 4y +9

5y²+9

according to question,

subtract 5y²+9 from 14 + 2y + y²

14 + 2y + y² - ( 5y²+9 )

14 + 2y + y² -5y²- 9

- 4y² +2y+ 5
