Re: factoring completely
you can try these fator(8*p^3-r^6,p) or fator(8*p^3-r^6,r)

Subject: factoring completely
Hello
I own a TI89 and I am having a little trouble with completely factoring
polynomials. I have cleared variables a-z so that is not part of the
problem.
I want to Factor completely: 8p^3-r^6
So on the 89 I do: factor(8p^3-r^6)
The answer it gives me is: 8p^3-r^6
So it does not completely factor, the answer that it should give me is:
(2p-r^2)*(4p^2+2pr^2+r^4)
Is there anyway to make it do that? What am I missing?
When I try to factor something simple like: factor(x^2-64) I get (x+8)*(x-8)
which we all know is correct.
So if you have any idea on how to solve this problem please get back to me.
Thanks again
