Jody -If regular factoring does not work, your other two choices are (1) completing the square, or (2) use the quadratic equation.Hope this helps

The answer is (x+3)(x+3) but it does also factor by 1 so it could also just be 1(x^2+9x+3).  =)

but i dont see how you get that answer if you could help more let me know thanks

Jody -You are best to use the quadratic formula in this problem where a=1, b=9 and c=3.  Substitute these values into the quadratic formula (look the formula up in your Algebra book) and that will get you the answers you are looking for.

so i got x= -9+√69      or    x=  -9-√69                       2                              2   is that all the farther that i can go???

Jody -Great work!  Yes, that is as far as you have to go unless your teacher wants you to provide approximate decimal answers.
