<p>this one is from barron's:
if the graph of 3x^2 + 4y^2 -6x + 8y - 5 + 0 and ( x - 2 )^2 = 4( y + 2 ) are drawn on the same co -ordinate system at how many points do they intersect?
(a)0
(b)1
(c)2
(d)3
(e)4
how do i do this sum with only a scientific calci..
my tutor showed me the method of plotting the two equations and then see where the lines intersect but it takes too longg...</p>
