x-12/3-x=x+14/x+4

Solution for x-12/3-x=x+14/x+4 equation:

D( x )

x = 0

x = 0

x = 0

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

x-x-(12/3) = x+14/x+4 // - x+14/x+4

x-x-x-(14/x)-(12/3)-4 = 0

x-x-x-14*x^-1-4-4 = 0

-1*x^1-14*x^-1-8*x^0 = 0

(-1*x^2-8*x^1-14*x^0)/(x^1) = 0 // * x^2

x^1*(-1*x^2-8*x^1-14*x^0) = 0

x^1

-x^2-8*x-14 = 0

-x^2-8*x-14 = 0

DELTA = (-8)^2-(-14*(-1)*4)

DELTA = 8

DELTA > 0

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

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

x in { (2*2^(1/2)+8)/(-2), (8-2*2^(1/2))/(-2)} 

x in { (2*2^(1/2)+8)/(-2), (8-2*2^(1/2))/(-2) }
