Quartic Equation Calculator
English

A default form of quartic equation is ax4 + bx3 + cx2 + dx + e = 0. It is also called a biquadratic equation. It is a polynomial with the degree of 4, which means the largest exponent is 4. The Quartic equation might have real root or imaginary root to make up a four in total. The online quartic equation calculator is used to find the roots of the fourth-degree equations. Enter the equation in the Biquadratic equation solver and hit calculate to know the roots.

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 Quartic equation solver will help you to dynamically calculate the roots of the quartic equation. Calculating roots of Biquadratic equation is made easier using this online tool. The fourth-degree equations can be solved using different methods.
