Feb 23	comment	How do I get my equation to have the form $(x-a)^2 + (y-b)^2 + (z-c)^2-d = 0$? @ArtesThank you very much
Feb 23	comment	How do I get my equation to have the form $(x-a)^2 + (y-b)^2 + (z-c)^2-d = 0$? I want the equation has my form exactly, not $-25 + (-1 + x)^2 + (-2 + y)^2 + (-3 + z)^2$.

Jan 17	accepted	What's the difference between the following two codes?
Jan 16	comment	What's the difference between the following two codes? You try Solve[{( m x + y - 7 z)^2 == Cos[[Pi]/3]^2(x^2 + y^2 + z^2)(m^2 + 1^2 + 7^2), -10 <= m <= 10, 0 <= x <= 10, 0 <= y <= 10, 0 <= z <= 10}, {m, x, y, z}, Integers] The number of solutions are more your code.
Jan 16	comment	What's the difference between the following two codes? The first I typed Cos[Pi/3] and the second Cos[Pi/6]. If I change your code is Cos[Pi/6], I only get three solutions.
