WebSep 13, 2024 · Solve equations of third degree or higher (fourth degree, fifth degree…) Divide a polynomial between a binomial that is in the x-a form; Factor polynomials of third degree or higher (fourth degree, fifth degree…) Calculate the roots of polynomials of degree greater than or equal to 3; WebAug 28, 2016 · 1) Transform the equation to the form x 3 + 3 b x + c. I see you already did it. In your case you have the form y 3 + q y + r which is exactly the same. 2) Smartass trick: let y = w − b w. This transforms the equation into w 3 + c − b 3 w 3 = 0 which is a quadratic in w 3. So solve this 3) You now have a value for w. Can you find then a root now?
