Question

1. Subtract 5x2

– 6y2 + 8y – 5 from 7x2

– 5xy + 10y2 + 5x – 4y.​

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
