Question

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

Answer 1

what is the question ask?

Answer 2

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

Answer 3

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

Answer 4

oh ok that makes sense

Answer 5

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

Answer 6

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

Answer 7

so how do I set up the synthetic division?
