So far i have this x2 + 2x + y2 + 4y = 20 (x2 + 2x) + (y2 + 4y) = 20
H!!
The radius is r = sqrt(25) = 5

complete mr square twice, once for each term
I need help figuring it out though, i have no idea whatsoever ho to do this problem.
Can someone walk me through this please?
for each to complete the square, take the coefficient on the linear x, y term and add to that quantity half of its square
I honestly have no idea how to do that..
So do i have to figure out that equation? I honestly dont think ill be able to learn this, ive been trying for about an hour
(x^2 + 2x + 1^2 ) + (y^2 + 4y + 2^2) = 20 + 1^2 + 2^2 you take half the middle term and add the square of it , now you can do this (x+1)^2 + (y+2)^2 = 25
http://www.mathsisfun.com/algebra/completing-square.html
the center of a circle in that form is (x - h)^2 + (y - k)^2 = r^2 here C(h,k) = C(-1 , -2) and r is the square root of 25
so the radius is 25 and the center of the circle is 5?
since 5 is the square root of 25
the center is the point (h,k) or ( -1 , -2),, how far each point on the circle is away from that center; the radius, is the square root of 25, or 5
r^2 = 25 r = 5
i am so confused.....
after you complete the squares, you have an equation in the form of ... (x-h)^2 + (y-k)^2 = r^2 r= radius, and (h,k) = the center point
