  (d)  f(x) = (x -1)(x -3+√13)(x -3-√13)

Step-by-step explanation:

A graphing calculator shows that factoring out (x -1) gives ...

  f(x) = (x -1)((x -3)^2 -13)

The quadratic factor will have roots ...

  x = 3±√13

so the remaining factors are ...

  f(x) = (x -1)(x -3+√13)(x -3-√13)

_____

A root of p means (x -p) is a factor.
