Solving cubic polynomials
WebAug 20, 2014 · Accepted Answer: Star Strider. I am using the command. x = solve ('a*x^3 + b*x^2 + c*x + d') to get the polynomial's roots. It returns a symbolic answer. Then i evaluate the a,b,c,d and i do copy-paste the first symbolic answer and then "enter" to get a numerical answer. The numbers i get (1 almost real and 2 complex, as it is expected) are not ...

WebSo the hardest part of factoring a cubic polynomial in general is finding a real root. Once a root r r is found, the polynomial factors as f (x) = (x-r)g (x), f (x) = (x−r)g(x), where g (x) g(x) is quadratic, and quadratic polynomials can be factored easily via the quadratic formula.
