一元四次方程的解法在线计算器

四次方程的公式:
四次方程 : ax⁴ + bx³ + cx² + dx + e = 0
注意 : 让p和q是任何两个非零数的平方根

根.
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文章源自公式库网-https://www.gongshiku.com/html/201912/yiyuansicifangchengdejiefazaixianjisuanqi.html
