Solution for 2a-(5/a-1)=0 equation: 


D( a )

a = 0

a = 0

a = 0

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

2*a-(5/a)+1 = 0

2*a-5*a^-1+1 = 0

2*a^1-5*a^-1+1*a^0 = 0

(2*a^2+1*a^1-5*a^0)/(a^1) = 0 // * a^2

a^1*(2*a^2+1*a^1-5*a^0) = 0

a^1

2*a^2+a-5 = 0

2*a^2+a-5 = 0

DELTA = 1^2-(-5*2*4)

DELTA = 41

DELTA > 0

a = (41^(1/2)-1)/(2*2) or a = (-41^(1/2)-1)/(2*2)

a = (41^(1/2)-1)/4 or a = (-(41^(1/2)+1))/4

a in { (-(41^(1/2)+1))/4, (41^(1/2)-1)/4} 

a in { (-(41^(1/2)+1))/4, (41^(1/2)-1)/4 }
