f(x)= x3 – 3x2 – x + 3 is -1 what are the zeros

OpenStudy (anonymous):

what is the question ask?

OpenStudy (anonymous):

"is -1 what are the zeros" doe not parse

OpenStudy (anonymous):

One x-intercept of the graph of the cubic function f(x)= x3 – 3x2 – x + 3 is -1. What are the other zeros?

OpenStudy (anonymous):

oh ok that makes sense

OpenStudy (anonymous):

that means \[x^3 – 3x^2 – x + 3=(x+1)(\text{some quadratic})\] and your job is to find the quadratic then you can always find the zeros of a quadratic function with the formula if it does not factor

OpenStudy (anonymous):

you can find the quadratic be division long division is a pain, synthetic division is easier or you can just think it out

OpenStudy (anonymous):

so how do I set up the synthetic division?
