To determine the correct factored form of a polynomial with the given roots -7, 10i, and 13, we need to consider the following:

1. The root -7 gives the factor (x + 7) because when x = -7, the factor (x + 7) = (-7 + 7) = 0.

2. The root 13 gives the factor (x - 13) because when x = 13, the factor (x - 13) = (13 - 13) = 0.

3. The root 10i must have its conjugate -10i as a root as well. If x...
