In fact, the 1st equation is two-lines and the 2nd one is an ellipse
Since
-->
-->
is an ellipse centered at (1,0).
They may have at most 4 points of intersectins.
[The point is to cancel variable y]
Using complete squares to covert the 1st equation to:
...(1)
Keep the 2nd equation as before
...(2)
From(1),we have y-1 =
( +/-means postive or negative)
When y = x-1 + 1 = x, goto (2), we have
,hence x = 0 or 8/5 (why??)
Then,we get y = 0 or 8/5 (since y = x)
When y = -x+1 + 1 = -x+2, goto (2), we have
,
Or
,
Factoring:
So,x = 2/5 or 2
and then, y = 8/5 or 0.
Thus,the four points of intersection are
(0,0),(8/5,8/5), (2/5, 8/5), and (2,0)
The graphs as:
