Question

Complete the square in x and y to find the center and the radius of the given circle.

(1/2x^2)+(1/2y^2)+(5/2x)+10y+5=0

Pls include all steps.

Answer 1

(1/2x^2)+(1/2y^2)+(5/2x)+10y+5...
Youe equation is incomplete. But it does not prohibit me from helping you.
I believe that you mean:
(1/2)x^2 + (1/2)y^2 + (5/2)x + 10y + 5...
= (1/2)*(x^2 + 5x + (5/2)^2) + (1/2)*(y^2 + 20y +100) - (1/2)*(5/2)^2 - 50 + (5....)
= (1/2)*(x + 5/2)^2 + (1/2)*(y +10)^2 - (25/8) - 50 + (5....)
Now you may be able to do the rest.
