Solution for 18-3x=x2^1/2 equation: 


x in (-oo:+oo)

18-(3*x) = (x^(2^1))/2 // - (x^(2^1))/2

18-((x^(2^1))/2)-(3*x) = 0

18-((x^2)/2)-3*x = 0

18-1/2*x^2-3*x = 0

DELTA = (-3)^2-(-1/2*4*18)

DELTA = 45

DELTA > 0

x = (45^(1/2)+3)/(-1/2*2) or x = (3-45^(1/2))/(-1/2*2)

x = -(3*5^(1/2)+3) or x = -(3-3*5^(1/2))

x in { -(3*5^(1/2)+3), -(3-3*5^(1/2)) }
