Yes, that particular polynomial expression is not readily factored other than manual "try" methods.  The factors which do evenly divide the original polynomial are "(x-2)" and "(x+2)".  This begins with a visual inspection of the polynomial and identifying the prime factors and then I like to use Algebrator's Polynomial Wizard titled "Long division" to verify that an attempted factor does evenly divide the polynomial (leaving no remainder).

For example, choosing (x+5) as a factor does leave a remainder, yet (x-2) does evenly divide the polynomial.
