Polynomial Addition Calculator
How It Works
This polynomial addition calculator uses established formulas to provide accurate results.
The basic rule:
- (a₁x² + b₁x + c₁) + (a₂x² + b₂x + c₂)
- = (a₁+a₂)x² + (b₁+b₂)x + (c₁+c₂)
- Combine like terms: add coefficients of same degree
Results are estimates. Consult a professional for critical decisions.

How do you add polynomials?
Line up like terms (terms with the same variable and exponent) and add their coefficients. x² terms combine with x² terms, x terms with x terms, and constants with constants.
Does the order matter when adding polynomials?
No, polynomial addition is commutative. P + Q = Q + P. The result is the same regardless of order.
What are like terms?
Like terms have the same variable raised to the same power. For example, 3x² and -5x² are like terms, but 3x² and 3x are not.
