Answer 8

First put it like this:
(x^2+22x)+(y^2-14y)+49=0
now add a number inside paraentesis to make a perfect square. Remmeber also to substract that same number to keep equation unchanged:
(x^2+22x +121)+(y^2-14y+49)+49-121-49=0
this way we get:
(x+11)^2+(y-7)^2=121
do you recognize this equation?

Answer 9

Yes i recognize :D
