Use synthetic division to divide. Practice Problem 5 Given 8f x 4x3 10 x2 3x find f-1. Divide 2 3 8 x x.
Complete forms at right to perform your synthetic division. As you can see the remainder is 68Since I started with a polynomial of degree 3 and then divided by x 3 that is by a polynomial of degree 1 I am left with a polynomial of degree 2Then the bottom line represents the polynomial 3x 2 7x 24 with a remainder of 68. Then the numerator is written in descending order and if any terms are missing we need to use a zero to fill in the missing term.

Set up the synthetic division to solve as shown below. So if the remainder comes out to be 0 when you apply synthetic division then x - c is a factor of f x. If the leading coefficient is not a 1 then you must divide by the leading coefficient to turn the leading coefficient.
Synthetic Division Perform synthetic division to divide by a binomial in the form x - k Example. Polynomial division can be used to solve application problems including area. 2x 3 6x 2 - 17x 15 x.
Synthetic division is generally used however not for dividing out factors but for finding zeroes or roots of polynomials. Synthetic division is a shorthand or shortcut method of polynomial division in the special case of dividing by a linear factor -- and it only works in this case. The Remainder Theorem states that f c the remainder.
