The expanded form of a circle can be expressed through the standard equation (x-h)²+(y-k)²=r². In this equation, (h,k) denotes the center of the circle while r symbolizes the radius. The process to identify the expanded form involves squaring the binomials and simplifying them. This consequently results in an equation that includes terms for x², y², x, y, and a constant.
