x2 - (2x)2 = x2 - 4x2 = -3x2 x2 - 2x2 = -x2
x2 + x2 = 2x2 2x^2
7
It is a quadratic relationship which for every x, y is squared.
X2 A number to the second power is squared.
x2 - (2x)2 = x2 - 4x2 = -3x2 x2 - 2x2 = -x2
(X2) (X2) = X4 x squared multiplied by x squared is x raised to the 4th power.
x2 + x2 = 2x2 2x^2
x^3 - 121x
x2+y2
