Solution for (a+1)-2(1/a)=0 equation: 


D( a )

a = 0

a = 0

a = 0

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

a-(2*(1/a))+1 = 0

a-2*a^-1+1 = 0

1*a^1-2*a^-1+1*a^0 = 0

(1*a^2+1*a^1-2*a^0)/(a^1) = 0 // * a^2

a^1*(1*a^2+1*a^1-2*a^0) = 0

a^1

a^2+a-2 = 0

a^2+a-2 = 0

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

DELTA = 9

DELTA > 0

a = (9^(1/2)-1)/(1*2) or a = (-9^(1/2)-1)/(1*2)

a = 1 or a = -2

a in { -2, 1} 

a in { -2, 1 }
