如何计算Cubic Formula
learn.whatIsHeading
Cubic equation (ax³+bx²+cx+d=0) solver finds all roots using Cardano's formula; more complex than quadratic.
分步指南
- 1Input cubic coefficients a,b,c,d
- 2Apply Cardano's formula (complex procedure)
- 3Results show 1-3 real roots
例题解析
输入
x³ - 6x² + 11x - 6 = 0
结果
Roots: 1, 2, 3
常见错误注意事项
- ✕Using quadratic formula (wrong)
- ✕Not handling complex intermediate results
常见问题
When do complex roots occur?
Cubic always has ≥1 real root, but others may be complex conjugate pairs.
