The ellipse 18x^2+2x+y^2=1 has its center at the point (b,c) where b=____ and c=____?
x^2/a^2 + y^2/b^2 = 1
The Attempt at a Solution
I need it to be in the form x^2/a^2 + y^2/b^2 = 1, then I can easily determine the coordinates of the center. Did I do something wrong? How do I get to this form? Thanks.
(This is for my Calc. II class and I asked in two other forums and got nothing...but I figured you guys would know about this due to applications in astrophysics.)
