    A perfect square means that it is made by squaring an expression. So, for example,\[x^2+4x+4\]factors into \[(x+2)(x+2)\]which can then be written simply\[(x+2)^2\]In your question, can you factor it into something that can be squared to get the original expression?

    If you multiply those two together, what do you get?
