x+0.3(600)/x+600

Solution for x+0.3(600)/x+600 equation:

D( x )

x = 0

x = 0

x = 0

x in (-oo:0) U (0:+oo)

x+(0.3*600)/x+600 = 0

1*x^1+180*x^-1+600*x^0 = 0

(1*x^2+600*x^1+180*x^0)/(x^1) = 0 // * x^2

x^1*(1*x^2+600*x^1+180*x^0) = 0

x^1

x^2+600*x+180 = 0

x^2+600*x+180 = 0

DELTA = 600^2-(1*4*180)

DELTA = 359280

DELTA > 0

x = (359280^(1/2)-600)/(1*2) or x = (-359280^(1/2)-600)/(1*2)

x = (12*2495^(1/2)-600)/2 or x = (-12*2495^(1/2)-600)/2

x in { (-12*2495^(1/2)-600)/2, (12*2495^(1/2)-600)/2} 

x in { (-12*2495^(1/2)-600)/2, (12*2495^(1/2)-600)/2 }
