Solution for 4/q=q equation: 


D( q )

q = 0

q = 0

q = 0

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

4/q = q // - q

4/q-q = 0

4*q^-1-1*q^1 = 0

(4*q^0-1*q^2)/(q^1) = 0 // * q^2

q^1*(4*q^0-1*q^2) = 0

q^1

4-q^2 = 0

4-q^2 = 0

DELTA = 0^2-(-1*4*4)

DELTA = 16

DELTA > 0

q = (16^(1/2)+0)/(-1*2) or q = (0-16^(1/2))/(-1*2)

q = -2 or q = 2

q in { -2, 2} 

q in { -2, 2 }
