Best ResponseYou've already chosen the best response.0Not sure, I honestly don't understand at all. here are the multiple choice answers if it helps? But I need the explanation on how to do it.

Best ResponseYou've already chosen the best response.1The equation looks like this to me. \(\Large x  7x^{\frac{1}{3}} + 6 = 0\)

Best ResponseYou've already chosen the best response.1\(\Large x  7x^{\frac{1}{3}} + 6 = 0\) \(\Large x + 6 = 7x^{\frac{1}{3}}\) \(\Large (x + 6)^3 = (7x^{\frac{1}{3}})^3\) \(\Large (x + 6)^3 = 343x\) \(\Large (x + 6)(x^2 + 12x + 36) = 343x\) \(\Large x^3 + 12x^2 + 36x + 6x^2 + 72x + 216 = 343x\) \(\Large x^3 + 18x^2 + 108x + 216 = 343x\) \(\Large x^3 + 18x^2  235x + 216 = 0\)

Best ResponseYou've already chosen the best response.0\[7x ^{\frac{ 1 }{ 3 }} = x+6\]\[343x = x^3+18x^2+108x+216\]\[x^3+18x^2235x+216=0\]But neither 216 nor 216 is a root. Could there be something wrong with the question?

Best ResponseYou've already chosen the best response.1and then factoring that (x8)(x+27) so (x1)(x8)(x+27) or x = 1,8,27 where the heck does x = 216 or x = 216 come into play?

Best ResponseYou've already chosen the best response.1OMG I ANSWERED MY OWN QUESTION x = 216 x = (27)(8)

Best ResponseYou've already chosen the best response.1those dummies combined the x = 216 ___________ the answer is actually x = 1, x = 8, x = 27 but they thought it was a great idea to combine x =8 and x 27 together to make x=(8)(27) = 216 X_X!

Best ResponseYou've already chosen the best response.1yeah.. and if they knock points off, you can complain and use my work as evidence to show how wrong they are.
