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

a. 0
b. 1/7
c. 2 (it's not this one i tried)
d. 7/3

It is D. 7/3 because the rational root theorem states that when a root 'x' is written as a fraction x = p/q in lowest terms, p is an integer factor of the constant term (i.e. 7), and q is an integer factor of the coefficient of the first monomial (i.e. 9x^8).

the answer would be c ≈ 18.852*3.14= 6.286.28*3=18.85
