Cubic equation calculator
Cubic equation belongs to the third order where a is not equal to zero, ax3 + bx2 + cx + d = 0. Value X is called as the root of cubical equation provided it reduces to the right equality upon its substitution.
Some main methods of solution exist:
- Cardano formula (It is interesting that the scientist was the first to discover complex numbers);
- Reflexive method;
- Trigonometric Vieta formulas (founder of symbolic algebra);
- Bezout theorem.
It is on our site kalkulilo.net that the finding cubic root with the help of Viet-Cardano formula is being performed, it always has three roots. Use symbol “minus” to introduce the negative coefficient, for example -20. Only numbers are permitted to enter. To find out the solution of the equation of third order it is necessary to fill in the form and press the button.
