    Question I hope this is the right area for this question

    Find a polynomial with leading coefficient 1 and degee 3 that has -1,1,and 3 as roots. My answer after working it out was x^3-3x^2+x-3, I would like to know if that is right. Thanks for looking it over.

    Well,
    (x-1)(x+1)(x-3)
    Factor everything,
    (x^2-1)(x-3)
    One more time,
    x^3-x-3x^2+3=0
