Adding and Subtracting PolynomialsTo add and subtract polynomials, simply combine like terms.

Combine the coefficients.

DO NOT change the variables and their exponents!!!!Example AExample BExample CExample DExample EExample FExample GAdd the polynomialsExample HExample IExample JAdd the polynomialsExample KAdd the polynomialsMultiplying PolynomialsTo multiply polynomials, multiply each and every term in the first polynomial by each and every term of the second polynomial.

Combine like terms.The process for multiplying binomials remains the same. You multiply each term of the first binomial with each term of the second binomial.
