Concept explainers
To find:the rational and irrational zeros of the polynomial.
Answer to Problem 69RE
the zeros of the polynomial is
Explanation of Solution
Given information:
the polynomial is
concept used:
rational zero theorem,
Calculation:
The constant term is 36 and the leading coefficient is 6 so
The factors of 36are
Thus, the possible rational zeros of
the possible zeros of
Using synthetic division,
1 | 6 | -18 | 6 | -30 | 36 |
6 | -12 | -6 | -36 | ||
6 | -12 | -6 | -36 | 0 |
3 | 6 | -18 | 6 | -30 | 36 |
18 | 0 | 18 | -36 | ||
6 | 0 | 6 | -12 | 0 |
Factors:
The zeros of the polynomial is
