- Keep the highest degree terms
For Subtraction:
- Change signs of second polynomial
- Combine like terms
- Subtract coefficients of same degree terms
Common Examples
| First Polynomial | Operation | Second Polynomial | Result |
|---|---|---|---|
| 2x² + 3x - 1 | + | x² - 2x + 4 | 3x² + x + 3 |
| 3x³ - 2x + 1 | - | x³ + x - 2 | 2x³ - 3x + 3 |
| 4x² + 2x | + | -2x² + 3 | 2x² + 2x + 3 |
| x² - 1 | - | 2x² + 3x | -x² - 3x - 1 |
Tips
- Use proper notation (x² for x squared)
- Include all terms, even if coefficient is 1
- Write terms in descending order of degree
- Be careful with signs during subtraction
- Combine like terms properly
