To find:the all possible rational zeros by rational zeros theorem.

Answer to Problem 7E
The rational zeros are
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 and eliminating duplicates, so the all possible rational zeros:
Hence, the all possible zeros are
