Form A Polynomial With Given Complex Zeros Calculator

Introduction & Importance

Forming a polynomial with given complex zeros is a fundamental concept in algebra, with wide-ranging applications in mathematics, engineering, and physics. This calculator simplifies the process, allowing users to input complex zeros and generate the corresponding polynomial.

How to Use This Calculator

1. Enter complex zeros in the format ‘a+bi’ or ‘a-bi’, separated by commas.
2. Select the degree of the polynomial.
3. Click ‘Calculate’.

Formula & Methodology

The formula for forming a polynomial with complex zeros is based on the Factor Theorem and Vieta’s Formulas. Given complex zeros z_i, the polynomial P(z) is formed as:

P(z) = a(z – z₁)(z – z₂)…(z – z_n)

Real-World Examples

Example 1

Given complex zeros 1+2i and 3-4i, and degree 2:

P(z) = (z – (1+2i))(z – (3-4i)) = z² – 4z + 13i
