Answer:
C 1
Step-by-step explanation:
x-1/x-2 - x^2+4x-4/(x-2)(x+6)
rewrite: (x-1)(x+6)-(x^2 + 4x - 4)/(x-2)(x+6)
expand x^2+6x-x-6-x^2-4x+4/(x-2)(x+6)
collect like terms (x^2-x^2)+(6x-x-4x)+(-6+4)/(x-2)(x+6)
simplify x-2/(x-2)(x+6)
cancel x-2 and get 1/x+6
but that is the only answer I can get from this, so I believe many one, just because of the numerator
