Review:
Bairstow's Method
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Bairstow's method is an iterative numerical algorithm used to find the roots of a polynomial equation. It is particularly effective for factoring polynomials when real or complex roots are needed, and it operates by extracting quadratic factors through successive approximations, making it suitable for high-degree polynomials.
