x = 0
x = 0
x = 0
x in (-oo:0) U (0:+oo)
8*x-(3/x) = 10 // - 10
8*x-(3/x)-10 = 0
8*x-3*x^-1-10 = 0
8*x^1-3*x^-1-10*x^0 = 0
(8*x^2-10*x^1-3*x^0)/(x^1) = 0 // * x^2
x^1*(8*x^2-10*x^1-3*x^0) = 0
x^1
8*x^2-10*x-3 = 0
8*x^2-10*x-3 = 0
DELTA = (-10)^2-(-3*4*8)
DELTA = 196
DELTA > 0
x = (196^(1/2)+10)/(2*8) or x = (10-196^(1/2))/(2*8)
x = 3/2 or x = -1/4
x in { -1/4, 3/2}
x in { -1/4, 3/2 }
