USE Synthetic Division to evaluate your possible root to be tested! If you do not yet know how to use synthetic division, then use polynomial division with divisor, x-4. Review the Remainder Theorem so you know what the result means. 

The synthetic division for the given information:

4   |    1    5    -2    7
