Find the equation of the ellipse specified:

(a) foci (-2,1) (4,1) and minor axis 8

(b) vertices (+-4,0) (0,+-5)

can you explain how to do it?

Also this extra credit problem is getting me frustrated.

sketch the graph of the equation and indicate the center, the foci, and the length of axes.

2x squared + 3y squared + 12x -24y + 60= 0

do i need to group it and then factor? what would my next steps be?? thanks :)
