    complete the square

    find the polar equation of the curve x^2+y^2=2cx by first completing the square.
    How do I complete the square?
    I have not done it in this form before?
    Thanks

    $\displaystyle
    \begin{gathered}
    x^2 - 2cx + \underbrace {c^2 - c^2 }_{} + y^2 = 0 \hfill \\
    \left( {x - c} \right)^2 + y^2 = c^2 \hfill \\
    \end{gathered}
