What is x^14 minus x^6?

y^14 - y^6

y^14 = yxyxyxyxyxyxyxyxyxyxyxyxyxy 

y^6 = yxyxyxyxyxy

yxyxyxyxyxyxyxyxyxyxyxyxyxy - yxyxyxyxyxy = error

basically, this equation is impossible to simplify unless you substitute a number for x :/

sorry....

All you can with it is to re-write it in this form:

x^6 (x^8-1), and if you wanted to solve for x, then it has these values:

x=1, x=-1 and x=0

x^14 - x^6    remains just that, unless you want to factor it as :

x^6(x^8 - 1) = x^6(x^4 - 1)(x^4 + 1) =

x^6 (x^2 - 1)(x^2 + 1)(x^4 + 1)  =

x^6 ( x - 1)(x + 1)(x^2 + 1)(x^4 + 1)

Thank you all for the responses! I'll check in with my teacher tomorrow! :)
