Is it basically every factor of the constant divided by every factor of the first coefficient?

not complete the highest power is 3 so maximum of 3 roots if (x-a) is a factor then f(a) = 0 the constant is 10, what are the factors of 10 that will add up to 3 use 5 and 2 also need to pay attention to the signs
