Answer 2

Answer:

1)Step 1:-

(2x² - 3x + 5) + (5x² + 7x + 6)

2x² - 3x + 5 + 5x² + 7x + 6

2x² + 5x² - 3x + 7x + 5 + 6

7x² + 4x + 11.

Step 2:-

(7x² + 4x + 11) - (x² + x + 1)

7x² + 4x + 11 - x² - x - 1

7x² - x² + 4x - x + 11 - 1

6x² + 3x + 10.

2) Step 1:-

(9 + xy - x²) + (x² + 1)

9 + xy - x² + x² + 1

9 + 1 + xy - x² + x²

10 + xy.

Step 2:-

(x² + xy - 2) + (3xy + 7)

x² + xy - 2 + 3xy + 7

x² + xy + 3xy - 2 + 7

x² + 4xy + 5.

Step 3:-

(x² + 4xy + 5) - (10 + xy)

x² + 4xy + 5 - 10 - xy

x² + 4xy - xy + 5 - 10

x² + 3xy - 5.
