Answer:
7y² - 6y - 9
Step-by-step explanation:
First let us add what is asked
first addition
= (3y² + 2y - 1) + (-2y² + 3y - 5)
= y² + 5y + 6 (i)
second addition
= (5y² - 6y) + ( 3y² + 5y -3)
= 8y² - y - 3 (ii)
So the question asks us to subtract (i) from (ii)
so
= (8y² - y - 3) - ( y² + 5y - 6)
= 8y² - y - 3 - y² - 5y + 6 [Sign change 'cause of subtraction]
= 7y² - 6y + 3
