A circle is represented by the equation x^2 + 8x + y^2 - 12y = -29. Describe the algebraic techniques needed to rewrite the equation in standard form. Identify the center and radius of the circle. Show your work.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
