## What is a 4th order equation?

A quartic equation, or equation of the fourth degree, is an equation that equates a quartic polynomial to zero, of the form. where a ≠ 0. The derivative of a quartic function is a cubic function.

Then. We do 2x.

## What is Cardanos formula?

A formula for finding the roots of the general cubic equation over the field of complex numbers x3+px+q=0. Any cubic equation can be reduced to the above form.

## How do you solve a quintic equation?

Unlike quadratic, cubic, and quartic polynomials, the general quintic cannot be solved algebraically in terms of a finite number of additions, subtractions, multiplications, divisions, and root extractions, as rigorously demonstrated by Abel (Abels impossibility theorem) and Galois.

## How do you solve a 3 degree equation?

The general strategy for solving a cubic equation is to reduce it to a quadratic equation, and then solve the quadratic by the usual means, either by factorising or using the formula. are all cubic equations. Just as a quadratic equation may have two real roots, so a cubic equation has possibly three.
