Y = x^2+x-2/(x-1). -2 = -1*2, -1+2 = 1 = B.
(x-1)(x+2)/(x-1) = 0
x+2 = 0
X = -2.
solution: (-2, 0).
We have only one solution, because the Eq was divided by (x-1).
Test: Let X = -2.
y=x^2+x-2/|x-1|
I got the line x-int (-2,0) and y-int(0,-2), but what about the second line? do I just use other points to test the equation? thank you
