If you know the factors here is how you get the zeros. You take the factor and set it to zero and solve for x, for example (x+2)=0 add the two to the other side. Now you have x=-2 and that is your zero. this is how factors and zeros are connected. When using division to find the factor of the first step is is to graph the polynomial and find the easy zeros. Next you take the easy zeros and synthetic divide those zeros out so you can plug the function into the quadratic formula and you got all the zeros!
