(2x-1)/(x-2) + 3/(x-2) = (x-2) * (x+2)-1 | Brüche links addieren
(2x+2)/(x-2)= (x-2) * (x+2)-1 |*Hauptnenner (x-2)(x+2)
(2x+2)(x+2) = (x-2)^2
2x^2 + 4x + 2x + 4 = x^2 - 4x + 4
x^2 + 10x = 0
x(x+10) = 0
x1 = 0
x2 = -10
Kontrolle
(2x-1)/(x-2) + 3/(x-2) = (x-2) * (x+2)-1
x=0
(-1)/(-2) + 3/(-2) = (-2) * (2)-1
1/2 - 3/2 = -1 stimmt
x = -10
(-20-1)/(-10-2) + 3/(-10-2) =?= (-10-2) * (-10+2)-1 = -12/-8 = 1.5
(-20-1)/(-10-2) + 3/(-10-2)= -21/-12 + 3/-12 = -18/-12 = 1.5 stimmt
