Step-by-step explanation:
Let's simplify step-by-step.
(5x−5y+z)2−(5x+5y−z)2
Distribute:
=25x2+−50xy+10xz+25y2+−10yz+z2+−25x2+−50xy+10xz+−25y2+10yz+−z2
Combine Like Terms:
=25x2+−50xy+10xz+25y2+−10yz+z2+−25x2+−50xy+10xz+−25y2+10yz+−z2
=(25x2+−25x2)+(−50xy+−50xy)+(10xz+10xz)+(25y2+−25y2)+(−10yz+10yz)+(z2+−z2)
=−100xy+20xz
