POLYNOMIAL FUNCTIONS A POLYNOMIAL is a monomial or a sum of monomials. A POLYNOMIAL IN ONE VARIABLE is a polynomial that contains only one variable. Example:

Perform the operation and write the result in standard form.( 6 – 2i )( 2 – 3i ) FOILFOIL 12 – 18i – 4i + 6i/ 2 12 – 22i + 6 ( -1 ) 6 – 22i We have seen that if a polynomial equation is of degree n, then counting multiple roots separately, the equation has n roots. This result is called the Fundamental Theorem of Algebra./

Dividing Polynomials Division of Polynomials Dividing Polynomials Long division of polynomials is similar to long division of whole numbers. dividend = (quotient divisor) + remainder /see this as f(x) = [q(x) ∙ (x – a)] + f(a). 2.The quotient is always a polynomial with one degree less than f(x). –Synthetic division is helpful in solving these problems (this can also be called synthetic substitution/
