## y=(x^2-1)/(x^2+2x-1)

y=(x^2-1)/(x^2+2x-1) is curve C

1. Show(without drawing) that line y=p (p is not 1) will always cross the curve C in two section, point A and B?

2. What should be the value of p so that point A and B always in the range of x>0?

I have solved problem no.1 but I'm not sure for problem no.2

Thanks
