Write a polynomial function in standard form with real coefficients

The evaluation of a polynomial consists of substituting a numerical value to each indeterminate and carrying out the indicated multiplications and additions. The third term is a constant. Similarly, an integer polynomial is a polynomial with integer coefficients, and a complex polynomial is a polynomial with complex coefficients.

The commutative law of addition can be used to rearrange terms into any preferred order. A polynomial of degree zero is a constant polynomial or simply a constant.

A polynomial in one indeterminate is called a univariate polynomial, a polynomial in more than one indeterminate is called a multivariate polynomial.

The term "quadrinomial" is occasionally used for a four-term polynomial. Unlike other constant polynomials, its degree is not zero. A polynomial with two indeterminates is called a bivariate polynomial.

Because the degree of a non-zero polynomial is the largest degree of any one term, this polynomial has degree two. The first term has coefficient 3, indeterminate x, and exponent 2. In the case of polynomials in more than one indeterminate, a polynomial is called homogeneous of degree n if all its non-zero terms have degree n.

The argument of the polynomial is not necessarily so restricted, for instance the s-plane variable in Laplace transforms. A real polynomial is a polynomial with real coefficients.

The polynomial 0, which may be considered to have no terms at all, is called the zero polynomial. The polynomial in the example above is written in descending powers of x.

For higher degrees the specific names are not commonly used, although quartic polynomial for degree four and quintic polynomial for degree five are sometimes used. These notions refer more to the kind of polynomials one is generally working with than to individual polynomials; for instance when working with univariate polynomials one does not exclude constant polynomials which may result, for instance, from the subtraction of non-constant polynomialsalthough strictly speaking constant polynomials do not contain any indeterminates at all.

The zero polynomial is homogeneous, and, as homogeneous polynomial, its degree is undefined. Polynomials of small degree have been given specific names. Polynomials of degree one, two or three are respectively linear polynomials, quadratic polynomials and cubic polynomials.

The names for the degrees may be applied to the polynomial or to its terms.Find a cubic polynomial in standard form with real coefficients having the given zeros.

Writing Polynomials in Standard Form

Write each polynomial in standard form. Then classify it by degree and by the number of terms. a. If the imaginary number abi is a root of a polynomial with real coefficients, the related polynomial function has exactly n zeros. When P(x) is a polynomial with real coefficients written in standard form.

•The number of positive real roots of P(x) = 0 is either equal to the number of sign changes between consecutive coefficients of P(x) or is less than that by an even number.
