Answer to Problem 34AYU
Here , the third row of synthetic division contains only numbers that are positive. Therefore is the upper bound.
Here , the third row of synthetic division contains only numbers that are alternating positive. Therefore is the lower bound.
Explanation of Solution
Given:
The degree of the polynomial is 3. Therefore the number of real zeros by real zero theorem can be at most .
Rational zeros theorem provides information about the potential rational zeros of a polynomial function with integer coefficients.
If in its lowest terms is a rational zero of , then is a factor of and is the factor of .
Here and .
Zeros of , .
Zeros of , .
The potential rational zeros of .
To find the upper bound, start with the smallest positive integer potential rational zero .
To find the lower bound start the largest negative integer potential rational zero .
Use repeated Synthetic division.
The coefficients are 3, , 1 and 4.
Coefficient of | Remainder | |
1 | 3, 1, 2 | 6 |
3, , 4 | 2 | |
3, , 20 |
