Document Summary
Long division can be used to divide a polynomial by a binomial. The result of the division of a polynomial function p(x) by a binomial of the form x b can be written as p(x) = (x-b)q(x) + r where q(x) is the quotient and r is the remainder. Division statement: divisor x quotient + remainder = dividend can be used to check the result of a division. For integer values of a and b, with a not equal 0, Factor theorem states that x b is a factor of a polynomial p(x) if and only if p(b) = 0. Similarly, if ax b is a factor of p(x) if and only if p(b/a) = 0. Integral zero theorem states that if x b is a factor of a polynomial function p(x) with leading coefficient 1 and remaining coefficients that are integers, then b is a factor of the constant term p(x).
