Solution for 8x-6/x=7 equation: 


D( x )

x = 0

x = 0

x = 0

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

8*x-(6/x) = 7 // - 7

8*x-(6/x)-7 = 0

8*x-6*x^-1-7 = 0

8*x^1-6*x^-1-7*x^0 = 0

(8*x^2-7*x^1-6*x^0)/(x^1) = 0 // * x^2

x^1*(8*x^2-7*x^1-6*x^0) = 0

x^1

8*x^2-7*x-6 = 0

8*x^2-7*x-6 = 0

DELTA = (-7)^2-(-6*4*8)

DELTA = 241

DELTA > 0

x = (241^(1/2)+7)/(2*8) or x = (7-241^(1/2))/(2*8)

x = (241^(1/2)+7)/16 or x = (7-241^(1/2))/16

x in { (7-241^(1/2))/16, (241^(1/2)+7)/16} 

x in { (7-241^(1/2))/16, (241^(1/2)+7)/16 }
