The fundamental theorem of algebra states that you will have n roots for an nth degree polynomial, including multiplicity. So, your roots for f (x) = x^2 are actually 0 (multiplicity 2). The total number of roots is still 2, because you have to count 0 twice. ( 48 votes) harry s ojeas md https://ciclosclemente.com

How do you find the roots of a 3rd degree polynomial?

WebWell you could probably do this in your head, or we could do it systematically as well. Subtract 1 from both sides, you get 2x equals negative 1. Divide both sides by 2, you get x is equal to negative 1/2. So when x equals negative 1/2-- or one way to think about it, p of negative 1/2 is 0. So p of negative 1/2 is 0.
