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
