Quartic Equation Calculator

To Calculate the roots:

For example, Enter a=3, b=6, c=-123, d=-126 and e=1080


ax4 + bx3 + cx2 + dx + e = 0
x4 + x³ + x² + x + e



Results:
x1: +   i
x2: +   i
x3: +   i
x4: +   i

 
   
  


Quartic Equation Formula:
Quartic Equation : ax4 + bx3 + cx2 + dx + e = 0
NOTE : Let p and q be the square root of any 2 non-zero roots.
p = sqrt(y1)
q = sqrt(y3)
r = -g / (8pq)
s = b / (4a)
  x1 = p + q + r - s
  x2 = p - q - r - s
  x3> = -p + q - r - s
  x4 = -p - q + r - s

This calculator will help you dynamically to calculate the roots of the quartic equation. Calculating roots of quartic equation is made easier.
