Answer 1

SOLUTION

TO CHOOSE THE CORRECT OPTION

Subtracting x²-y²+z² from x²-y²-z² the resultant expression is______

2x²

2y²

- 2z²

0

EVALUATION

Here the given expressions are

x²-y²+z² and x²-y²-z²

Now Subtracting x²-y²+z² from x²-y²-z² the resultant expression

= x² - y² - z² - ( x² - y² + z² )

= x² - y² - z² - x² + y² - z²

= - 2z²

FINAL ANSWER

Hence the correct option is - 2z²
