Resolfing of mathematical equations

# 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.

\$x^3+\$ \$x^2+\$ \$x+\$ \$=0\$

• Example:
• \$x^3\$+2\$x^2\$+2\$x\$+1\$=0\$
• \$x^3\$-2\$x^2\$+5\$x\$+3\$=0\$
• \$x^3\$+1\$=0\$
