Get into standard form
Homework Equations
The Attempt at a Solution
x^2 + 4y^2 - 2x - 32y = 0
Complete the square two times.
(x^2 - 2x + 1) +4(y^2 - 8y +16 )=0 + 4(16) + 1
Simplfy..
(x-1)^2 + 4(y-4)^2 =65
Try to get the equation...
Yeah, I'm really confused... My teacher wants an exact, decimal answer so I guess I'll just do it with my calc... but I really thought that was some way without it..

The Attempt at a Solution
Ok, so I put the log equation into exponential form.
It now becomes:
x^6=216
I'm lost on what to do next.. I've tried taking the e and ln of both sides, but when I check it, it's...
