Solution for x2/(0.05-x)=3.1*10^-8 equation: 


D( x )

0.05-x = 0

0.05-x = 0

0.05-x = 0

0.05-x = 0 // - 0.05

-x = -0.05 // * -1

x = 0.05

x in (-oo:0.05) U (0.05:+oo)

(x^2)/(0.05-x) = 3.1*10^-8 // - 3.1*10^-8

(x^2)/(0.05-x)-(3.1*10^-8) = 0

(x^2)/(0.05-x)-3.1*10^-8 = 0

(x^2)/(0.05-x)-0.000000031 = 0

(x^2)/(0.05-x)+(-0.000000031*(0.05-x))/(0.05-x) = 0

x^2-0.000000031*(0.05-x) = 0

x^2+0.000000031*x-0.00000000155 = 0

x^2+0.000000031*x-0.00000000155 = 0

x^2+0.000000031*x-0.00000000155 = 0

DELTA = 0.000000031^2-(-0.00000000155*1*4)

DELTA = 0.0000000062

DELTA > 0

x = (0.0000000062^(1/2)-0.000000031)/(1*2) or x = (-0.0000000062^(1/2)-0.000000031)/(1*2)
