    Simplifying Radicals

    Hello, could any one here give me a step by step on how to solve this problem?

    sqrt( 4x^2 + 8x + 4 )

    I know the answer is 2x+2, I just don't know how to do it.

    Is this \displaystyle \begin{align*} \sqrt[3]{2x-6} \end{align*}? If so, it doesn't simplify...
