The rational root theorem is used to determine the potential roots of a function.

The potential roots are: [tex]\mathbf{-10, -5, 3, 15}[/tex]

The function is given as:

[tex]\mathbf{P(x) = x^3 + 6x^2 - 7x - 60}[/tex]

For a polynomial function:

[tex]\mathbf{P(x) = px^n +.............+ q}[/tex]

The potential roots are:

[tex]\mathbf{Roots = \pm \frac{Factors\ of\ q}{Factors\ of\ p}}[/tex]

The factors of 60 are:

[tex]\mathbf{60 = \pm 1, \pm 2, \pm 3, \pm 4, \pm 5, \pm 6, \pm 10, \pm 12, \pm 15, \pm 20, \pm 30, \pm 60}[/tex]

The factor of 1 is:

[tex]\mathbf{1 = \pm 1}[/tex]

So, we have:

[tex]\mathbf{Factors= \frac{\pm 1, \pm 2, \pm 3, \pm 4, \pm 5, \pm 6, \pm 10, \pm 12, \pm 15, \pm 20, \pm 30, \pm 60}{\pm 1}}[/tex]

[tex]\mathbf{Factors= \pm 1, \pm 2, \pm 3, \pm 4, \pm 5, \pm 6, \pm 10, \pm 12, \pm 15, \pm 20, \pm 30, \pm 60}[/tex]

The potential roots in the option are:

[tex]\mathbf{Factors= -10, -5, 3, 15}[/tex]
