Final answer:

To get x²-y²+z² from 2x²-5y²+7z², we need to subtract x²+y²-6z².


Step-by-step explanation:

To get x²-y²+z² from 2x²-5y²+7z², we need to subtract x²+y²-6z². Let's break it down:

2x² - x² = x²

-5y² - y² = -6y²

7z² - 6z² = z²

So, we subtract x²+y²-6z² from 2x²-5y²+7z² to get x²-y²+z².
