Question 235893
<font face="Garamond" size="+2">


If 3 is a zero of P(x), then (x - 3) is a factor of P(x).  Use polynomial long division to divide P(x) by (x - 3).  The quotient, set equal to zero, will be a factorable quadratic equation which, when solved, will give you the other two zeros of P(x).


Below are two sites that illustrate polynomial long division
