# Quartic Equation Calculator

Calculate the roots for given equation.

The quartic equations are those equations that have highest exponent is 4, means as an equation of degree 4 as follows:

ax^{4} + bx^{3} + cx^{2} + dx + e = 0,

where

a, b, c and d are the coefficients and

e is constants.

### For example,

ax^{4} + bx^{3} + cx^{2} + dx + e = 0 is a quartic equation

where

a = 1, b = 2, c = -41, d = -42 and e = 360
