Solution for 4/n=n/16 equation: 


D( n )

n = 0

n = 0

n = 0

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

4/n = n/16 // - n/16

4/n-(n/16) = 0

4*n^-1-1/16*n^1 = 0

(4*n^0-1/16*n^2)/(n^1) = 0 // * n^2

n^1*(4*n^0-1/16*n^2) = 0

n^1

(-1/16)*n^2+4 = 0

(-1/16)*n^2+4 = 0

DELTA = 0^2-(4*4*(-1/16))

DELTA = 1

DELTA > 0

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

n = -8 or n = 8

n in { -8, 8} 

n in { -8, 8 }
