Find intersection points of the following.(Conics are centered to origin)
Circle = x^2+y^2=4, Ellipse = (x^2/4)+(y^2/9) = 1
The Attempt at a Solution
So far I have this. (BTW I know the solutions are (-2,0) and (2,0) but I'm still unsure how to get there step by step).
(x^2/4)+(y^2/4) = (x^2/4)+(y^2/9)= 1
What's the next step?
