    x^4 + x + 6

    Partial factor

    x( x³ + 1 ) + 6

    Sum of two cubes formula

    x( x + 1 )( x² - x + 1 ) + 6

    I hope this helps you. Have a good day.

    This isn't factorable, in fact, it has four complex roots. Even if you meant x^2 + x + 6, this too cannot be factored (and gives two complex roots).

    Source(s): You can plug in your expression here to numerically find the zeros: http://www.wolframalpha.com/widgets/view.jsp?id=a7... You should notice that all 4 are complex.
