Solution for 3/a=a-2 equation: 


D( a )

a = 0

a = 0

a = 0

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

3/a = a-2 // - a-2

3/a-a+2 = 0

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

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

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

a^1

2*a-a^2+3 = 0

2*a-a^2+3 = 0

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

DELTA = 16

DELTA > 0

a = (16^(1/2)-2)/(-1*2) or a = (-16^(1/2)-2)/(-1*2)

a = -1 or a = 3

a in { -1, 3} 

a in { -1, 3 }
