Solution for (12*x-5*x*x-1)/(3*x-3)=0 equation: 


D( x )

3*x-3 = 0

3*x-3 = 0

3*x-3 = 0

3*x-3 = 0 // + 3

3*x = 3 // : 3

x = 3/3

x = 1

x in (-oo:1) U (1:+oo)

(12*x-(5*x*x)-1)/(3*x-3) = 0

(12*x-5*x^2-1)/(3*x-3) = 0

12*x-5*x^2-1 = 0

12*x-5*x^2-1 = 0

DELTA = 12^2-(-5*(-1)*4)

DELTA = 124

DELTA > 0

x = (124^(1/2)-12)/(-5*2) or x = (-124^(1/2)-12)/(-5*2)

x = (2*31^(1/2)-12)/(-10) or x = (-2*31^(1/2)-12)/(-10)

(x-((2*31^(1/2)-12)/(-10)))*(x-((-2*31^(1/2)-12)/(-10))) = 0

((x-((2*31^(1/2)-12)/(-10)))*(x-((-2*31^(1/2)-12)/(-10))))/(3*x-3) = 0

( x-((-2*31^(1/2)-12)/(-10)) )

x-((-2*31^(1/2)-12)/(-10)) = 0 // + (-2*31^(1/2)-12)/(-10)

x = (-2*31^(1/2)-12)/(-10)

( x-((2*31^(1/2)-12)/(-10)) )

x-((2*31^(1/2)-12)/(-10)) = 0 // + (2*31^(1/2)-12)/(-10)

x = (2*31^(1/2)-12)/(-10)

x in { (-2*31^(1/2)-12)/(-10), (2*31^(1/2)-12)/(-10) }
