For what values of x and y is the equation (x2 + y2)2 = (x2 – y2)2 + (2xy)2 true?

Answer

For any values of x and y is the equation(x2 + y2)2 = (x2 – y2)2 + (2xy)2  is true

Solution

Consider the identities

(a + b)^2 = a2 + b2 +2ab  (1)

(a - b)^2 = a2 + b2 -2ab   (2)

from (1) and (2) we can write

(a + b)^2 = (a - b)^2 + 4ab

Here a=x2 and b=y2

(x2 + y2)2  = (x2)2 + (y2)2 +2x2y2

(x2 - y2)2  = (x2)2 + (y2)2 -2x2y2

Therefore  

(x2 + y2)2 = (x2 – y2)2 + (2xy)2  

For any values of x and y is the equation (x2 + y2)2 = (x2 – y2)2 + (2xy)2  is true

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:
