x = 0
x = 0
x = 0
x in (-oo:0) U (0:+oo)
x+3/x-8 = 0
1*x^1+3*x^-1-8*x^0 = 0
(1*x^2-8*x^1+3*x^0)/(x^1) = 0 // * x^2
x^1*(1*x^2-8*x^1+3*x^0) = 0
x^1
x^2-8*x+3 = 0
x^2-8*x+3 = 0
DELTA = (-8)^2-(1*3*4)
DELTA = 52
DELTA > 0
x = (52^(1/2)+8)/(1*2) or x = (8-52^(1/2))/(1*2)
x = (2*13^(1/2)+8)/2 or x = (8-2*13^(1/2))/2
x in { (8-2*13^(1/2))/2, (2*13^(1/2)+8)/2}
x in { (8-2*13^(1/2))/2, (2*13^(1/2)+8)/2 }
