expressions in quadratic form: 6b^5 + 3b^3 - 1

[skydreamer]

OK I understand the basic concept, but I got one problem on my homework that just doesn't work, no matter what I do. Can you help? I'm supposed to write each expression in quadratic form, if possible.

6b^5+3b^3-1

Thank you

Re: expressions in quadratic form

This quintic has 4 non real and only one real root. That is why you are having trouble.

It does not factor nicely.
