Math 1513 Sec R.3 1 Section R.3 Addition, Subtraction, and Multiplication of Polynomials Polynomials are algebraic expressions that we will deal with often in this course. Hopefully, you are very familiar with them and the material in this section will be a review. Polynomials consist on one or more terms that are added or subtracted together. Each term of the polynomial has the same basic form. It may begin with a coefficient (a real number) that is multiplied by the variable term. It contains one or more variables ( x, y, z , etc.) The variables may be raised to powers and these powers must be nonnegative integers. A polynomial in one variable looks like: 1 2 1 2 1 0 ... n n n n n n a x a x a x a x a Not all terms need to be present. Also, some of the signs may be negative. The highest power of the variable that is present in the polynomial is called the degree of the polynomial . The coefficient of the term with the highest power is called the leading coefficient . If the terms are written in order from the highest power of the variable to the lowest power, the polynomial is said to be written in descending order .
