x^2y^2-R^2s^2=

Solution for x^2y^2-R^2s^2= equation:

Simplifying
x2y2 + -1R2s2 = 0

Reorder the terms:
-1s2R2 + x2y2 = 0

Solving
-1s2R2 + x2y2 = 0

Solving for variable 's'.

Move all terms containing s to the left, all other terms to the right.

Add '-1x2y2' to each side of the equation.
-1s2R2 + x2y2 + -1x2y2 = 0 + -1x2y2

Combine like terms: x2y2 + -1x2y2 = 0
-1s2R2 + 0 = 0 + -1x2y2
-1s2R2 = 0 + -1x2y2
Remove the zero:
-1s2R2 = -1x2y2

Divide each side by '-1R2'.
s2 = x2y2R-2

Simplifying
s2 = x2y2R-2

Take the square root of each side:
s = {-1xyR-1, xyR-1}
