WebThe gist is as follows: When you have a cubic of the form a x 3 + b x + c = 0 (which you do), substitute u + v = x in for x subject to 3 u v = − b. Plugging this in and simplifying, you see that u 3 and v 3 are the two roots of the equation z 2 + c z − b 3 27 = 0. Then you may solve for u and v with the quadratic formula and a cubic root. WebMar 30, 2024 · The term real root means that this solution is a number that can be whole, positive, negative, rational, or irrational.
