Divide the function by x-5 to produce a quadratic quotient.

Through synthetic division:

5____|_____-1______7_____-9______-5
_____|
_____|___________-5______10______5
_____|_____-1______2_____1_______0

Note carefully the coefficients according to the bottom row:

Find the roots to this resulting polynomial using solution to quadratic formula.
