Question 859693
<font face="Times New Roman" size="+2">


If 1 is a zero, then *[tex \LARGE x\ -\ 1] must be a factor of the polynomial.  Use polynomial long division to divide the original polynomial by *[tex \LARGE x\ -\ 1].  The quotient will be a quadratic polynomial that will factor into two linear factors.

My calculator said it, I believe it, that settles it
