    \[x^3 + x^2 + 3x + 10 = 0\]

    u can start guessing the possible zeros based on the coefficients. I forgot how this method is called

    Isn't there something called some rational roots theorem? I can't figure it out.

    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

    Decartes rule of sign 3 positive roots or 2 negative and one real positive
