Canonical form:
4y^2+z^2-x-16y-4z+20=0
x2a2+y2b2+z2c2=1
x^2+y^2+2x+6y+6=0
x-exp(-x)
Plot:
x^2+(y-(sqrt((|x|))))^2=1
x^2+(y-(sqrt(x))^3*(x^2))^2=1
sqrt(x^2-0,36)/x-2
tan(x*y)=1
Identical expressions
z=- one -sqrt(two -x^ two -y^ two)
z equally minus 1 minus square root of (2 minus x squared minus y squared )
z equally minus one minus square root of (two minus x to the power of two minus y to the power of two)
z=-1-√(2-x^2-y^2)
z=-1-sqrt(2-x2-y2)
z=-1-sqrt2-x2-y2
z=-1-sqrt(2-x²-y²)
z=-1-sqrt(2-x to the power of 2-y to the power of 2)
z=-1-sqrt2-x^2-y^2
Similar expressions
z=-1+sqrt(2-x^2-y^2)
z=-1-sqrt(2-x^2+y^2)
z=+1-sqrt(2-x^2-y^2)
z=-1-sqrt(2+x^2-y^2)

z=-1-sqrt(2-x^2-y^2) canonical form

The teacher will be very surprised to see your correct solution 😉

1 + z + \/  2 - x  - y   = 0

$$z + \sqrt{- x^{2} - y^{2} + 2} + 1 = 0$$

z + sqrt(-x^2 - y^2 + 2) + 1 = 0
