1. Input the Polynomial Expression: Enter the polynomial you wish to add or subtract. Ensure you correctly format the expression, e.g., 2x^2 + 3x – 5.
2. Select the Operation: Choose whether you want to add or subtract another polynomial.
3. Enter the Second Polynomial: Input the second polynomial in the provided field.
4. Calculate: Click the ‘Calculate’ button to get the result.
5. Review the Result: The output will show the final polynomial expression after performing the chosen operation.

Formula

The fundamental formulas for adding and subtracting polynomials are straightforward:

• Addition: (a_n*x^n + a_(n-1)*x^(n-1) + … + a_0) + (b_n*x^n + b_(n-1)*x^(n-1) + … + b_0) = (a_n + b_n)x^n + (a_(n-1) + b_(n-1))x^(n-1) + … + (a_0 + b_0)
• Subtraction: (a_n*x^n + a_(n-1)*x^(n-1) + … + a_0) – (b_n*x^n + b_(n-1)*x^(n-1) + … + b_0) = (a_n – b_n)x^n + (a_(n-1) – b_(n-1))x^(n-1) + … + (a_0 – b_0)

Example Calculation

Let’s consider a practical example:

Polynomial A: 3x^2 + 4x – 7

Polynomial B: 2x^2 – x + 5

To Add:

• Combine like terms: (3x^2 + 2x^2) + (4x – x) + (-7 + 5)
• Result: 5x^2 + 3x – 2

To Subtract:

• Combine like terms: (3x^2 – 2x^2) + (4x – (-x)) + (-7 – 5)
• Result: x^2 + 5x – 12
