5/a-2/1-a=2/a-1

Solution for 5/a-2/1-a=2/a-1 equation:

D( a )

a = 0

a = 0

a = 0

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

5/a-a-(2/1) = 2/a-1 // - 2/a-1

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

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

3*a^-1-1*a^1-1*a^0 = 0

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

a^1*(3*a^0-1*a^2-1*a^1) = 0

a^1

3-a^2-a = 0

3-a^2-a = 0

DELTA = (-1)^2-(-1*3*4)

DELTA = 13

DELTA > 0

a = (13^(1/2)+1)/(-1*2) or a = (1-13^(1/2))/(-1*2)

a = (13^(1/2)+1)/(-2) or a = (1-13^(1/2))/(-2)

a in { (13^(1/2)+1)/(-2), (1-13^(1/2))/(-2)} 

a in { (13^(1/2)+1)/(-2), (1-13^(1/2))/(-2) }
