Where:
- P(x) is the first polynomial
- Q(x) is the second polynomial
- R(x) is the resulting polynomial after the operation
Step-by-Step Breakdown of the Formula
To understand how to add or subtract polynomials effectively, follow this detailed breakdown:
- Identify the Polynomials: First, determine the two polynomials you wish to add or subtract.
- Align Like Terms: Write the polynomials in a column format aligning like terms (i.e., terms with the same degree).
- Add/Subtract the Coefficients: For each set of like terms, add or subtract their coefficients accordingly.
- Combine Constants: Add or subtract constant terms to get the final constant in ( R(x) ).
- Write the Result: Express the resulting polynomial in standard form (from highest degree to lowest degree).
Example Calculation
Let’s work through an example to show how the “Adding and Subtracting Polynomials Calculator” utilizes this formula.
Example Input of Polynomials
| Polynomial P(x) | Polynomial Q(x) |
|---|---|
| 3x² + 5x + 2 | 2x² – 4x + 3 |
Adding the Two Polynomials
- Aligning like terms:
| 3x² | + 5x | + 2 |
|---|---|---|
| 2x² | – 4x | + 3 |
- Combine like terms:
| Resulting Polynomial R(x) |
|---|
| (3x² + 2x²) + (5x – 4x) + (2 + 3) = 5x² + 1x + 5 |
Subtracting the Two Polynomials
- Aligning like terms:
| 3x² | + 5x | + 2 |
|---|---|---|
| 2x² | – 4x | + 3 |
- Combine like terms:
| Resulting Polynomial R(x) |
|---|
| (3x² – 2x²) + (5x + 4x) + (2 – 3) = 1x² + 9x – 1 |
