Adding Polynomials Calculator

A polynomial is a function which has any variable raised to an exponent. A polynomial function can have only positive integer exponents and a polynomial can consist of a single term, two terms or more than two terms. Adding polynomials calculator is an online tool used to add polynomial function together.

Example 1: Add the given two polynomial functions, f(x) = 2x² + 3x – 1 and g(x) = 4x² – 5x + 7
f(x) + g(x) = (2x² + 3x – 1) + (4x² – 5x + 7)

Now combine the like terms in the polynomial functions   add the terms with the exponent ‘2’ together and the terms with the exponent ‘1’ together and the constants together!

f(x) + g(x) = (2x² + 4x²) + (3x -5x) + (-1 + 7)

f(x) + g(x) = 6x² -2x + 6


Example 2: Add the given two polynomial functions, f(x) = x⁴ – 2x³ + 4x² – 8x + 6 and g(x) = x³ – 3x² + 5x – 4.

f(x) + g(x) = (x⁴ – 2x³ + 4x² – 8x + 6) + (x³ – 3x² + 5x – 4)

Now combine the like terms è add the terms with the similar exponents only!

f(x) + g(x) = x⁴ + (-2x³ + x³) + (4x² – 3x²) + (-8x + 5x) + (6 – 4)

 f(x) + g(x) = x⁴ – x³ + x² – 3x + 2
