Complete the square on 
: Divide the coefficient on the first degree term by 2, square the result, and add that result to both sides of the equation.

Simplify the right hand side. The RHS will be the radius squared. Take the positive square root of the RHS to get the radius. Multiply by 2 to get the diameter.
