Use the simple Quartic formula provided below to find the roots of a biquadratic equation. In quartic equation formula, the largest exponent is four ie, 4^{th}degree equation. The equation is ax^{4} + bx^{3} + cx^{2} + dx + e = 0. Here a, b, c and d are the root values. Quartic is the polynomial which can be solved using any of the methods such as factoring, completing the square, rational root theorem, using a graphing calculator, or by using the quadratic formula.

NOTE : Let p and q be the square root of any 2 non-zero roots.

p = sqrt(y

q = sqrt(y

r = -g / (8pq)

s = b / (4a)

In this Quartic formula, there will be four complex solutions and it could have real and imaginary roots to make up a total of four. Use the quartic equation formula for your personal reference.
