Question

x^2 + 2x + y^2 + 4y = 9. What is the center?

Answer 1

An explanation of how to find it would also be very helpful because I have another like this. Thank you. (:

Answer 2

Sorry I thought it was Radius
Center = (-g,-f)

Answer 3

standard equation is

\[x^2 + y^2 + 2gx + 2fy +c = 0 \]

Answer 4

Now when we compare coefficient g=1 and f =2

Answer 5

so that makes center \[(-1,-2)\]

Answer 6

x^2+2x+1+y^2+4y+4=9+1+4
(x+1)^2+(y+2)^2=14
center is (-1,-2)
