1. The problem statement, all variables and given/known data Show that the equation represents a sphere, and find its center and radius. 3x2+3y2+3z2 = 10+ 6y+12z 2. Relevant equations 3. The attempt at a solution 3x2+3y2-6y +3z2 -12z =10 My equation is how the constants in-front of the squared terms affect the sphere formula? Besides that I should be completing the square for the Y and Z terms right?
