Solution for (x^2)/(1-x)=0,67 equation: 


D( x )

1-x = 0

1-x = 0

1-x = 0

1-x = 0 // - 1

-x = -1 // * -1

x = 1

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

(x^2)/(1-x) = 0.67 // - 0.67

(x^2)/(1-x)-0.67 = 0

(x^2)/(1-x)+(-0.67*(1-x))/(1-x) = 0

x^2-0.67*(1-x) = 0

x^2+0.67*x-0.67 = 0

x^2+0.67*x-0.67 = 0

x^2+0.67*x-0.67 = 0

DELTA = 0.67^2-(-0.67*1*4)

DELTA = 0.67^2+2.68

DELTA = 3.1289

DELTA > 0

x = ((0.67^2+2.68)^(1/2)-0.67)/(1*2) or x = (-(0.67^2+2.68)^(1/2)-0.67)/(1*2)

x = ((0.67^2+2.68)^(1/2)-0.67)/2 or x = (-((0.67^2+2.68)^(1/2)+0.67))/2

(x+((0.67^2+2.68)^(1/2)+0.67)/2)*(x-(((0.67^2+2.68)^(1/2)-0.67)/2)) = 0

((x+((0.67^2+2.68)^(1/2)+0.67)/2)*(x-(((0.67^2+2.68)^(1/2)-0.67)/2)))/(1-x) = 0

((x+((0.67^2+2.68)^(1/2)+0.67)/2)*(x-(((0.67^2+2.68)^(1/2)-0.67)/2)))/(1-x) = 0 // * 1-x

(x+((0.67^2+2.68)^(1/2)+0.67)/2)*(x-(((0.67^2+2.68)^(1/2)-0.67)/2)) = 0

( x+((0.67^2+2.68)^(1/2)+0.67)/2 )

x+((0.67^2+2.68)^(1/2)+0.67)/2 = 0 // - ((0.67^2+2.68)^(1/2)+0.67)/2

x = -(((0.67^2+2.68)^(1/2)+0.67)/2)

( x-(((0.67^2+2.68)^(1/2)-0.67)/2) )

x-(((0.67^2+2.68)^(1/2)-0.67)/2) = 0 // + ((0.67^2+2.68)^(1/2)-0.67)/2

x = ((0.67^2+2.68)^(1/2)-0.67)/2

x in { -(((0.67^2+2.68)^(1/2)+0.67)/2), ((0.67^2+2.68)^(1/2)-0.67)/2 }
