Rational Root Theorem, q/p
The Attempt at a Solution
Hello everyone. Today, I've learned the rational root theorem( it's a bit late, isn't it? :( ) and thus wanted to see how it works. According to the rational root theorem the roots must be ± 1, but wolframalpha says the roots are x ≈ 0.672378 and x ≈ 3.23402. ( It also says there're also complex roots, but it's not what I'm looking for).
What am I doing wrong?
