Question 203724
x^2 + 4y^2=4  --> 4y^2 = 4 - x^2
(x-1)^2+y^2=1 --> 4x^2 - 8x + 4 + 4y^2 = 4
-------------
Sub for 4y^2 into 2nd eqn
4x^2 - 8x + 4 + (4-x^2) = 4
3x^2 - 8x + 4 = 0
*[invoke solve_quadratic_equation 3,-8,4]
x = 2
x = 2/3
----------
at x=2: y = 0
--> (2,0) One solution
----------
at x = 2/3: y = +/- sqrt(8)/3
--> (2/3,y) 2nd point/solution
--> (2/3,-y) 3rd point/solution
