What is the completely factored form of f(x)=x3−7x2+2x+4? f(x)=(x−1)(x−(3+52−−√−(3−52−−√)) f(x)=(x+1)(x−(3+13−−√−(3−13−−√)) f(x)=(x+1)(x−(3+52−−√−(3−52−−√)) f(x)=(x−1)(x−(3+13−−√−(3−13−−√))

  (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.
