## Quartic Polynomial

A quartic polynomial is characterized as an equation having highest power of 4th degree.

This quartic equation roots calculator uses Ferrari’s solution for quartic equations.

The quartic equation formula reduces the equation to two quadratic equations and there by further finding roots of the quadratic equations.

Quartic equation formula is also derived by many other renowned mathematicians like Euler.

The method is solution by radicals.

## How to use:

Using this quartic equation roots calculator is very simple.

Just input the coefficients of quartic equation which are ‘a’, ‘b’, ‘c’, ‘d’ and ‘e’.

This equation calculator can also be converted to solve cubic equations and quadratic equations.

If a=0, the polynomial turns into a cubic equation and the calculator is capable of finding cubic equation roots also.

If a=0 and b=0, the polynomial turns into quadratic equation which can also be solved using this calculator.
