Question

Which of the following cannot be a root of the polynomial 9x5 + ax3 +b, where a and b are integers. a. 9 b. -9 c. 1/3 d. 1/4

Answer 1

To determine which value cannot be a root of the polynomial, substitute each value into the equation and check if it equals zero.

Step-by-step explanation:

To determine which of the given values cannot be a root of the polynomial, we can substitute each value into the polynomial equation and check if it equals to zero. Let's substitute the values: a = 9 and b = 1/3.

For a = 9, we get 9(9)^5 + 9x^3 + b. This is a valid root since it satisfies the polynomial equation.

For b = 1/3, we get 9x^5 + ax^3 + 1/3. This is also a valid root since it satisfies the polynomial equation.

Now, let's substitute the remaining values and check for validity.
