Answer 2

Given : Subtracting x²-y²+z² from x²-y²-z²

To find : The resultant expression.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the resultant expression)

Here, we will be using general method of algebraic subtraction.

In this case,

• Minuend = x²-y²-z²
• Subtrahend = x²-y²+z²

And, we know that :

Minuend - Subtrahend = Difference

So, the given subtraction will be :

= (x²-y²-z²) - (x²-y²+z²)

= (x²-y²-z²-x²+y²-z²)

= -2z²

(This will be considered as the final result.)

Hence, the resultant expression is -2z²
