According to the rational root theorem, the following are potential roots of f(x) = 6x^4 + 5x^3 – 33x^2 – 12x + 20.

-5/2, -2, 1, 10/3

which is an actual root of f(x)?
a. -5/2
b. –2
c. 1
d. 10/3

                             Option A

Step-by-step explanation:

Given that a function,

f(x) = 6x⁴ + 5x³ - 33x² - 12x + 20

put the numbers in place of x, if function become 0 it means that number is root of the given function.

For

So, is the root of given function.

That's the final answer.
