Solution for ((x+4)/(x-1))+((x^2+x)/(x-1)) equation: 


D( x )

x-1 = 0

x-1 = 0

x-1 = 0

x-1 = 0 // + 1

x = 1

x in (-oo:1) U (1:+oo)

(x+4)/(x-1)+(x^2+x)/(x-1) = 0

x^2+x+x+4 = 0

x^2+2*x+4 = 0

x^2+2*x+4 = 0

x^2+2*x+4 = 0

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

DELTA = -12

DELTA < 0

1 = 0

1/(x-1) = 0

1/(x-1) = 0 // * x-1

1 = 0

x belongs to the empty set
