Solution for x+x^(1/2)-56=0 equation: 


D( x )

x < 0

x < 0

x in <0:+oo)

x+x^(1/2)-56 = 0

t_1 = x^(1/2)

1*t_1^2+1*t_1^1-56 = 0

t_1^2+t_1-56 = 0

DELTA = 1^2-(-56*1*4)

DELTA = 225

DELTA > 0

t_1 = (225^(1/2)-1)/(1*2) or t_1 = (-225^(1/2)-1)/(1*2)

t_1 = 7 or t_1 = -8

t_1 = -8

x^(1/2)+8 = 0

1*x^(1/2) = -8 // : 1

x^(1/2) = -8

( -8 < 0 i 1/2 in (0:1) ) => x naleu017Cy do O

t_1 = 7

x^(1/2)-7 = 0

1*x^(1/2) = 7 // : 1

x^(1/2) = 7

x^(1/2) = 7 // ^ 2

x = 49

x = 49
