What Polynomial Arithmetic Means

Polynomial arithmetic combines like terms to produce a simplified result. It is the foundation for many algebraic manipulations.

How to Add and Subtract Polynomials

  1. Group terms with matching exponents.
  2. Distribute the negative sign when subtracting.
  3. Combine coefficients of like terms.
  4. Write the result in descending order of powers.
result = combine like terms

Worked Example

Example: (3x^2 + 2x + 5) + (x^2 - 4x + 1) = 4x^2 - 2x + 6.

3x^2 + 2x + 5 + x^2 - 4x + 1 = 4x^2 - 2x + 6

Frequently Asked Questions

What are like terms?

Like terms have the same variable part raised to the same power.

Can coefficients be decimals?

Yes. Real-number coefficients are supported.

What if a term is missing?

A missing term can be treated as having coefficient zero.

Does the order matter?

The standard display order is highest exponent to lowest exponent.
