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)

What is the area of the region x plus y squared equals 56 when x plus y equals 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.
X squared plus y squared plus z if x equals 7 y equals 6 and z equals 4?
89
Factor y squared plus y-56?
(y + 8)(y - 7)
If x squared minus y squared equals 10 and x plus y equals 5 what is x minus y?
2
What is the value of k when y equals 3x plus 1 and is a line tangent to the curve of x squared plus y squared equals k?
k = 0.1
