    This should be pretty straight forward to factor. What's causing the problem?

    4(x^2+6x+9)=0

    To factor you are going to undo the foil process. \[x^2 + (a+b)x + ab = (x+a)(x+b)\]

    So you are looking for two numbers (a and b) that will add together to give you 6, and multiply to make 9.

    Did you figure out which numbers you have for a and b?
