Solution for 0.26=((0.3-x)^2)/(0.2-x) equation: 


D( x )

0.2-x = 0

0.2-x = 0

0.2-x = 0

0.2-x = 0 // - 0.2

-x = -0.2 // * -1

x = 0.2

x in (-oo:0.2) U (0.2:+oo)

0.26 = ((0.3-x)^2)/(0.2-x) // - ((0.3-x)^2)/(0.2-x)

0.26-(((0.3-x)^2)/(0.2-x)) = 0

(-1*(0.3-x)^2)/(0.2-x)+0.26 = 0

(-1*(0.3-x)^2)/(0.2-x)+(0.26*(0.2-x))/(0.2-x) = 0

0.26*(0.2-x)-1*(0.3-x)^2 = 0

0.34*x-x^2-0.038 = 0

0.34*x-x^2-0.038 = 0

0.34*x-x^2-0.038 = 0

DELTA = 0.34^2-(-1*(-0.038)*4)

DELTA = 0.34^2-0.152

DELTA = -0.0364

DELTA < 0

1 = 0

1/(0.2-x) = 0

1/(0.2-x) = 0 // * 0.2-x

1 = 0

x belongs to the empty set
