I hate factoring...

Haha. Start by gathering all x's and y's like before. I'm going to factor the x terms too.\[9(x^2+4x)+y^24y=31\] Then complete the squares, remembering what every you add to the x's, you have to multiply by 9, then add that to the other side.\[9(x^2+4x+4)+(y^24y+4)=31+4+(9 \times 4)\] Then factor the perfect squares...\[9(x+2)^2+(y2)^2=9\] Then divide everything by 9 and you end up with your answer.

so, (x+2)^2/1 + (y2)^2/9 ? @rkfitz053
