In algebra, polynomial long division is an algorithm for dividing a polynomial by another polynomial of the same or lower degree, a generalised version of the familiar arithmetic technique called long division.It can be done easily by hand, because it separates an otherwise complex division problem into smaller ones. We can write a polynomial dividend as the product of the divisor and the quotient added to the remainder. Always match the leading terms exactly 2. Notice that there's no x²-term, so we need to be careful during the long division. Compare long division and synthetic division Of polynomials. Polynomial Long Division in Algebra 2 A while back I shared a reference sheet for students learning how to divide polynomials using synthetic division. Synthetic division is a short-cut. I think it is important for students to master long division with numbers before they try to tackle polynomial division. Synthetic division is a shorthand method of dividing polynomials for the special case of dividing by a linear factor whose leading coefficient is 1.. To illustrate the process, recall the example at the beginning of the section. There are two ways to divide polynomials but we are going to concentrate on the most common method here: The algebraic long method or simply the traditional method of dividing algebraic expression.. Algebraic Long Method Instruct high school students to divide each term of the polynomial individually by the monomial divisor. Reduce the fractions in each term, and apply the quotient rule that says the exponents should be subtracted when dividing two powers with the same base.
