Subject: factoring ^6

my name is Athena and I have a question on factoring: how would you figure this out:

(x6-y6) and (x6+y6)

i'm a student in 9th grade algebra 2

Hi Athena,

What you have to do here is to see x6 as (x2)3 and y6 as (y2)3. Maybe it helps to write a for x2 and b for y2, then

x6 - y6 = a3 - b3 and x6 + y6 = a3 + b3

Now factor a3 - b3 and a3 + b3. When you are finished that step substitute x2 for a and y2 for b and see if you can continue factoring.
