Question

Subtracting x 2 - y 2 + z2 from x2 - y 2 - z 2 , the resultant expression is ______​

Answer 1

Answer:

-2z²

Step-by-step explanation:

(x² - y² - z²) - (x² - y² + z²)

=> x² - y² - z² - x² + y² - z²

=> -2z²

Answer 2

Subtracting x² - y² + z² from x² - y² - z² , the resultant expression is - 2z²

Given :

The expressions x² - y² + z² and x² - y² - z²

To find :

The resultant expression when x² - y² + z² is subtracted from x² - y² - z²

Solution :

Step 1 of 2 :

Write down the given expressions

Here the given expressions are

x² - y² + z² and x² - y² - z²

Step 2 of 2 :

Find the resultant expression when x² - y² + z² is subtracted from x² - y² - z²

Subtracting x² - y² + z² from x² - y² - z² we get the resultant expression

= (x² - y² - z²) - (x² - y² + z²)

= x² - y² - z² - x² + y² - z²

= - 2z²
