Examples of Polynomials
Linear and quadratic equations are examples of polynomials. These were studied in earlier units. The following are also examples of polynomials:
Notice that the terms are written in descending order of the variables' exponents. The polynomial, 4x3 + 2x2 - x + 5, has four terms. The coefficient of 4x3 is 4, the coefficient of 2x2 is 2, the coefficient of -3x is -3, and the constant is 1.
