  2. Guidelines for Adding, Subtracting, and Multiplying Polynomials Adding Polynomials Subtracting Polynomials Multiplying Polynomials When multiplying two polynomials, you are just using the distributive property multiple times. When multiplying two binomials, this is called the FOIL method. Parentheses do not change the problem. Combine like terms – variable(s) must raised to the same power – if so, combine coefficients. Exponents do not change. All signs for each term must be switched in the set of parentheses that follow the subtraction sign. Then follow the rules for adding polynomials. - Examples - - Examples - - Examples - (2x2 – 4x + 4) + (–2x2 – 5x + 4) = (2x2 – 4x + 4) – (–2x2 – 5x + 4) = (2x2 – 4x + 4) (–2x2 – 5x + 4) = (7x3 + 6x2 – 2x) + (9x2 – 4x + 3) = (7x3 + 6x2 – 2x) – (9x2 – 4x + 3) = (4x – 5) (3x + 7) =
