Question 742494: What is a polynomial with a single root at x = -6 and a triple root at x = -1? Answer by fcabanski(1391) (Show Source): You can put this solution on YOUR website! When a root is at x=a then the factor is x-a. So for x=-6 the factor is x+6, and for x=-1 the factor is x+1. Multiplicity 3 means there are three factors (x+1).
Multiply the factors together to see the polynomial.
