To state: that how to use the rational root theorem with an equation that has rational coefficients.
Answer to Problem 21WE
By find the total possible rational roots and then by using synthetic division.
Explanation of Solution
Given information:
The equation has rational coefficients.
in the equation with rational coefficients, use the rational root theorem,
First find the factor of highest degree term and constant term and then divide constant term factors by highest degree term factors and then simplify them and they are the total possible rational roots.
Then by using synthetic division, the root of the equation can be obtained.
