Best ResponseYou've already chosen the best response.0multply both sides by x^3 factor (x^21)(x^2+1) and again (x^21) = (x+1)(x1) set to zero x+1=0 x1=0 What are your roots??? (x^2+1) can never be 0 when y=0 x is?? see graph

Best ResponseYou've already chosen the best response.2okay so move x^3 to the right side as ~zpupster said multiply both sides by x^3

Best ResponseYou've already chosen the best response.0Okay so then it would be \[x ^{3} \times (x ^{4}  1) \div x ^{3} = 0\]

Best ResponseYou've already chosen the best response.0But the x^3 can be cancelled so... the answer would be:\[x ^{4}  1 = 0\]

Best ResponseYou've already chosen the best response.2yep you need to multiply *both sides* so 0 times x^3 = 0 now apply difference of square rule

Best ResponseYou've already chosen the best response.2yep right you would apply difference when there is negative sign so x^21 apply difference of square
