D( x )
x-2 = 0
x-2 = 0
x-2 = 0
x-2 = 0 // + 2
x = 2
x in (-oo:2) U (2:+oo)
1200/(x-2) = 803 // - 803
1200/(x-2)-803 = 0
1200/(x-2)+(-803*(x-2))/(x-2) = 0
1200-803*(x-2) = 0
2806-803*x = 0
(2806-803*x)/(x-2) = 0
(2806-803*x)/(x-2) = 0 // * x-2
2806-803*x = 0
2806-803*x = 0 // - 2806
-803*x = -2806 // : -803
x = -2806/(-803)
x = 2806/803
x = 2806/803
