In mathematics, a quartic function, is a function of the form ax4 + bx3 + cx2 + dx + e = 0.
where a is nonzero, which is defined by a polynomial of degree four, called quartic polynomial.
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
