Question

subtract 5x²-6y²+7y-4 from 7x²-5xy+10y²​

Answer 1

Answer:

5x² – 6y² + 8y – 5 from 7x² – 5xy + 10y² + 5x – 4y

(7x² – 5xy + 10y² + 5x – 4y) - (5x² – 6y² + 8y – 5)

= 7x² – 5xy + 10y² + 5x – 4y - 5x² + 6y² - 8y + 5

= 7x² - 5x² - 5xy + 10y² + 6y² + 5x - 4y - 8y + 5

= 2x² - 5xy + 16y² + 6y² + 5x - 12y + 5

Answer 2

Step-by-step explanation:

(7x² - 5xy + 10y²) - (5x² - 6y² + 7y - 4)

= 7x² - 5xy + 10y² - 5x² + 6y² - 7y + 4

= 2x² - 5xy + 16y² - 7y + 4
