4a^2c^2 - (a^2 - b^2 +c^2)^2 Factor this completely My attempt is to expand then foil the right side of the equation, then I'm stuck. For whatever reason, I haven't been able to concentrate on this question. I just am missing a fact or two. I would like it if you could show me step by step the process which you solve it. I am about to flap my hands around and run in circles I am so frustrated with this. lol. Thank you.
