(a)A polynomial is written without powers of x by factoring out x from thenon-constant terms.Given:A fourth-degree polynomial in x such as contains all of the powers of x from the first through the fourth.However, any polynomial can be written without powers of x. Evaluatinga polynomial without powers of x (Horner's method) is somewhat easierthan evaluating a polynomial with powers.Calculation:A polynomial is written in the form, Which is arranged from thehighest to the lowest degree of x.Now, x is factored out from the non-constant terms of the polynomial,and proceeding in this manner, a polynomial can be written as withoutthe power of x.Therefore, a polynomial is written without powers of x by factoring out x from the non-constant terms.(b)The new form uses addition and multiplication to evaluate a polynomial.Given:A fourth-degree polynomial in x such as contains all of the powers of x from the first through the fourth.However, any polynomial can be written without powers of x. Evaluatinga polynomial without powers of x (Horner's method) is somewhat easierthan evaluating a polynomial with powers.Calculation:A polynomial is written in the form, Which is arranged from thehighest to the lowest degree of x.Now, the new form uses precisely addition and multiplication in thesame manner as that of the synthetic division to evaluate a polynomial.Therefore, the new form uses addition and multiplication to evaluate apolynomial.
