Best ResponseYou've already chosen the best response.1ok.. so this is an equation that can be written as a quadratic use a substitution \[u = x^{\frac{1}{3}}\] so the equation is \[4u^2  11u  3 = 0\] this can be factored to (4u + 1)(u  3) = 0 so then solve for u... does that make sense so far...?

Best ResponseYou've already chosen the best response.0So I can do substitution? Okay

Best ResponseYou've already chosen the best response.1yes... that is the easiest method to solve this equation when you get the solutions for u, then let the solutions equal \[x^{\frac{1}{3}}\]

Best ResponseYou've already chosen the best response.0Yes I know that.. I assumed I couldn't solve that way since it didnt say I could

Best ResponseYou've already chosen the best response.1well it will give the real solutions... I'd always treat questions of this type as quadratics.... so you need to solve \[x^{\frac{1}{3}} = \frac{1}{4},~~and~~~~, x^{\frac{1}{3}} = 1\]
