Formula and methodology
Formula: Align coefficients by power, then add or subtract corresponding terms.
The coefficient lists make the polynomial structure explicit and preserve zero coefficients when powers are missing.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- First coefficients, highest power first
- Second coefficients, highest power first
- Operation — 2 choices
Worked example
| Input | Value |
|---|---|
| First coefficients, highest power first | 1,2,3 |
| Second coefficients, highest power first | -1,0,2 |
| Operation | add |
Result coefficients =0,2,5; polynomial =2x+5.
Assumptions and limits
- Coefficients are finite decimal numbers separated by commas and listed from highest power to constant.
- The operation applies to complete polynomials; blank entries and symbolic variables are not parsed.
- The result is normalized by removing leading zero coefficients.
