Concept explainers
To find: the all rational zeros of polynomial and write the polynomial in factored form.

Answer to Problem 18E
The rational zeros are
Factored form of polynomial is
Explanation of Solution
Given information:
The polynomial is
Concept used: rational zero theorem,
Calculation:
By the rational zeros theorem the rational zeros of
The constant term is
The factors of
Thus, the possible rational zeros of
Simplify the fractions, so the all possible rational zeros:
For the rational zeros, substitute the x values by the possible rational zeros in the polynomial,
The rational zeros are
So the factored polynomial is ,
