Solution for X-4=(2x)^(1/2) equation: 


D( x )

2*x < 0

2*x < 0

2*x < 0

2*x+0 < 0 // - 0

2*x < 0 // : 2

x < 0/2

x < 0

x in <0:+oo)

X-4 = (2*x)^(1/2) // - (2*x)^(1/2)

X-(2*x)^(1/2)-4 = 0

-2^(1/2)*x^(1/2) = -(X-4) // : -2^(1/2)

x^(1/2) = (4-X)/(-2^(1/2))

x^(1/2) = (4-X)/(-2^(1/2)) // ^ 2

x = ((4-X)^2)/2

x = ((4-X)^2)/2
