Question 890552
One would imagine you want or should want to use Rational Roots Theorem and try to factor the polynomial.  Use synthetic division to check for possible roots of -1,-2,-4,1,2,4.


A quick check using the graphing finding feature of google indicates or suggests ONLY one real root, and it is near, slightly above x=9.  The equation does not have any rational roots.  Solving for x using the usual number properties will not be too helpful.  Try approximating for x numerically.
