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:
ax4 + bx3 + cx2 + dx + e = 0, where a, b, c and d are the coefficients and e is constants.
For example, ax4 + bx3 + cx2 + dx + e = 0 is a quartic equation where a=1, b=2, c=-41, d=-42 and e=360

x4 + x³ + x² + x + e
