factoring===================== 1. 16x^3 - 54 This one, I've broken it to 2(2^3 x^3 - 3^2) but it's still wrong! I don't get how much further it can be broken down! 2. 3x^4 - 48 This one.. I've gotten far as 3x^2 (x^2 - 4x + 4) ! Still wrong. ============================= Zeros... dang it I'm kinda embarrassed to even ask... 1. 9x^3 + 27x^2 = 4x - 12 I've put x = -3, but I know there's more. I don't know how to get more! 2. x^5 - 100x = 0 Dang it, I don't know the zero of this one >< ! THANK YOU!!
