WebTo solve a polynomial equation write it in standard form (variables and canstants on one side and zero on the other side of the equation). Factor it and set each factor to zero. … WebSachin. 9 years ago. 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)
