Solution for x-3x^(1/2)-18=0 equation: 


D( x )

x < 0

x < 0

x in <0:+oo)

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

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

t_1 = x^(1/2)

1*t_1^2-3*t_1^1-18 = 0

t_1^2-3*t_1-18 = 0

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

DELTA = 81

DELTA > 0

t_1 = (81^(1/2)+3)/(1*2) or t_1 = (3-81^(1/2))/(1*2)

t_1 = 6 or t_1 = -3

t_1 = -3

x^(1/2)+3 = 0

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

x^(1/2) = -3

( -3 < 0 i 1/2 in (0:1) ) => x należy do O

t_1 = 6

x^(1/2)-6 = 0

1*x^(1/2) = 6 // : 1

x^(1/2) = 6

x^(1/2) = 6 // ^ 2

x = 36

x = 36
