The remainder theorem is a method for dividing polynomials using Euclidean division. It states that when a polynomial, f(x), is divided by a linear polynomial, x - a, the remainder of that division will be equivalent to f(a).  The remainder theorem can be used to: Factor polynomials of any degree Determine if a value is a root of a polynomial  The factor theorem is a special case of the remainder theorem. The factor theorem states that if f(a) = 0, then the binomial (x).  Some properties of the remainder theorem include: The remainder is always less than the divisor If the remainder is... Show more
