Verified answer

(7y^2 - 6y + 5) - (4y^2 - 2y + 3)

= 7y^2 - 6y + 5 - 4y^2 + 2y - 3

= 7y^2 - 4y^2 - 6y + 2y + 5 - 3

= 3y^2 - 4y + 2

(7y² - 6y + 5) - (4y² - 2y + 3)

You may only subtract the numbers with numbers, numbers with y with numbers with y, numbers with y² with numbers with y²:

7y² - 6y + 5 - 4y² + 2y - 3

Answer: 3y² - 4y + 2

(7y^2 - 6y + 5) - (4y^2 - 2y + 3)

7y^2 - 6y + 5 - 4y^2 + 2y - 3

7y^2 - 4y^2 - 6y + 2y + 5 - 3

3y^2 - 4y + 2

3y² - 4y + 2
