Hello, I'm absolutely stuck. :S My teacher gave me these 'challenge' problems and I have no idea how to get started. Can somebody explain how to start each equation? (Not solving it would be okay. I would love to get the answer...just don't know how to start it).

It means that if you make the substitution you get the quadratic:Originally Posted by nathan02079
and so:
is satisfied on , where are the roots of , which now needs to be translated into something to do with
.
Consider:
The rational root theorem suggests that if this has rational roots then they are either or , test these. If one or other of these are roots then and/or are factors of , so take out the factors and see what that transforms:
into, and draw any conclusions.
(what this should do, if you get it right, is lead you to find all the real roots of then the inequality will be satisfied between appropriate consecutive pairs of these roots)
