Question

X²-y²-2z-2y=0M⁰=(-1;-1;1)​

Answer 1

Подставляем (x−1)2−1 вместо x2−2x в уравнение x2−2x+y2−2y=0.(x−1)2−1+y2−2y=0

Answer 2

It looks like you've provided an equation and a point, but it's not entirely clear what you're asking for. The equation you've given is:

x² - y² - 2z - 2y = 0

And the point you've provided is:

M⁰ = (-1, -1, 1)

It seems like you might be looking for some specific information related to this equation and point. Are you looking to solve for certain variables, find the equation of a plane, or something else? Please provide more context or clarify your question so I can assist you accurately.
