Solution for (x/3+y/5)^3-(x/3-y/5)^3 equation:


x in (-oo:+oo)

(x/3+y/5)^3-(x/3-(y/5))^3 = 0

(1/3*x+1/5*y)^3-1*(1/3*x-1/5*y)^3 = 0

(1/3*x+1/5*y)^3-1*(1/3*x-1/5*y)^3 = 0

2/15*x^2*y+2/125*y^3 = 0

2/15*x^2*y+2/125*y^3 = 0

2/15*x^2*y = -(2/125*y^3) // : 2/15*y

x^2 = -3/25*y^2

x^2 = -3/25*y^2 // ^ 1/2

abs(x) = (-3/25)^(1/2)*y

x = (-3/25)^(1/2)*y or x = -((-3/25)^(1/2)*y)

x in { (-3/25)^(1/2)*y, -((-3/25)^(1/2)*y) }
