y2 + y2 - 56 let's factor it such as
= 2y2 - 56
= 2(y2 - 28)
= 2[y2 - (√28)2]
= 2(y - √28)(y + √28)
= 2(y - √4*7)(y + √4*7)
= 2(y - 2√7)(y + 2√7)
If by area you mean X*Y it would be -49 (or 49, if you assume area to be positive). (X=7, Y=-7) when X+Y^2=56 and X+Y=0.

If by area you mean X*Y it would be -49 (or 49, if you assume area to be positive). (X=7, Y=-7) when X+Y^2=56 and X+Y=0.

(2, -2)
They are +/- 5*sqrt(2)
(x, y) = (-3, -3) or (3, 3)
They touch each other at (0, 100) on the x and y axis.
y equals x plus 4 when y equals 0 then x equals 2i i is the square root of negative 1
no you smell
It is the equation of a parabola.
