āYour teacher asks the class to factor x4 ā x3 completely and apply the difference of cubes formula. Your friend says this canāt be done, because the expression is not a difference of cubes. Is your friend correct? Explain
Your friend is correct because you can factor out an xĀ³ form both terms but that will leave you with xĀ³(x-1) which is not the difference of two cubes
