1 1 P.3 POLYNOMIALS Objectives:  Operations on polynomials  Applications of polynomials ( كثيرات الحدود )

2 A polynomial in one variable is an algebraic expression of the form ( معاملات ) ( معامل الحد الاكبر أس ) ( درجة )

3 A monomial in one variable is the product of a constant times a variable raised to a nonnegative integer power. Thus, a monomial is of the form where a is a constant, x is a variable, and k > 0 is an integer. A polynomial of two terms is a binomial. A polynomial of three terms is a trinomial. 7xy 2 + 2y 8x 2 + 12xy + 2y 2

4 4 Polynomials The constant term is 15. The degree is 3. The leading coefficient is 6. The leading coefficient of a polynomial is the coefficient of the variable with the largest exponent. 6x 3 – 2x 2 + 8x + 15 The constant term is the term without a variable. The degree of a polynomial is the greatest of the degrees of any of its terms. The degree of a term is the sum of the exponents of the variables.
