Question

Which of the following represents the set of possible rational roots for the

polynomial shown below?
2x + 5.82 - 81 - 10=0

Answer 1

The rational root of the given polynomial is 42.59.

Explanation:

The polynomial is given by 2x + 5.82 - 81 - 10 = 0

or, 2x + 5.82 - 91 = 0

or, 2x = 85.18

or, x = 42.59.

The rational roots of any polynomial = the ratio of the factors of constants and factors of leading coefficients.
