Solution for 4/n+2=7-n equation: 


D( n )

n = 0

n = 0

n = 0

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

4/n+2 = 7-n // - 7-n

n+4/n-7+2 = 0

1*n^1+4*n^-1-5*n^0 = 0

(1*n^2-5*n^1+4*n^0)/(n^1) = 0 // * n^2

n^1*(1*n^2-5*n^1+4*n^0) = 0

n^1

n^2-5*n+4 = 0

n^2-5*n+4 = 0

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

DELTA = 9

DELTA > 0

n = (9^(1/2)+5)/(1*2) or n = (5-9^(1/2))/(1*2)

n = 4 or n = 1

n in { 1, 4} 

n in { 1, 4 }
