According to the rational root theorem, which number is a potential root of f(x) = 9x8 + 9x6 – 12x + 7?

All the potential root of f(x) are .

Step-by-step explanation:

According to the rational root theorem, all the potential root of f(x) are defined as

Where, p is factor of constant term and q is factor of leading coefficient.

The given function is

Here, constant term is 7 and leading coefficient is 9.

Factors of 7 are ±1, ±7 and the factors of 9 are ±1, ±3, ±9.

Using rational root theorem, all the potential root of f(x) are

Therefore all the potential root of f(x) are .

answer: it is d
