The answer is true...
Why?
Let's take (2x) as a simple polynomial. Subtracting 2x from 2x is one thing, then adding it's inverse, (-2x) yields the equation to 0. This is why it is true...
Hope this helps!! Please give me brainliest!
The distance between both points is 11
X - 3y + z
Another term would be the 3rd term which would be working with 3d planes instead of 2d planes.
