Answer 1

Answer:

This is a algebraic expressions so, firstly we have to write the equations and finally add them

Answer 2

Answer:

-x² -y²-6

Step-by-step explanation:

x² - y² - 5 + y² - 6 - x² + 5 - x² - y²
First step:
Regroup like terms (used brackets for convenience purpose):

(x² - x² - x²)(- y² + y² - y²) (- 5 - 6 + 5)

Second step:
Solve:
x² - x² - x² = -1x² or -x²
-y² + y² - y² = - 1y² or - y²

- 5 - 6 + 5 = - 11 + 5 = - 6

Third step:
Arrange in systematical order:

∴ Final result:

- x² - y² - 6
