The first power is one less than the highest power of the polynomial that was being divided. Correct answers will move you ahead incorrect answers are highlighted in red and require correction before you advance to the next input cell.

Write the coefficients of the dividend to the right. We can use synthetic division to divide polynomials if the degree in the divisor is equal to 1 and if the coefficient of the variable in the divisor is equal to 1. In order to divide polynomials using synthetic division you must be dividing by a linear expression and the leading coefficient first number must be a 1.

We can simplify the division by detaching the coefficients. Multiply and add Example. After we do this we can write the coefficients of the divisor and dividend and use synthetic division to determine the answer.

2x4 4x2 - 1 by x -1 Fill in missing terms. You can then use synthetic division to check if x-k is a factor of the polynomial. For example we can factor x 2 - 2x - 3 as.

X 4 x 3 x 2 x 1 x 0 5 1 5 7 34 1. An easy way to do this is to first set it up as if you are doing long division and then set up your synthetic division. 43 2 1 2237 2 xx x x x 2 5.

Evaluate x 3 8x 3 x 3 using synthetic division. Because the remainder is zero this means that x 3 is a factor and x 3 is a zero. In this lesson we will look at Synthetic Division which is simplified form of long division.

Which of the following statements is are shown by the synthetic division for this problem shown below. Divide 5 x4 6 x3 9 x2 7 x 6 by x 2 using the synthetic method. That means using x 2 so a 2.

Solve the following problems using synthetic division. Sign in with Office365. The reduced polynomial and remainder will be provided for you when the synthetic division has been completed correctly.

Write the problem in a division-like format. If we divide a polynomial such as x 2 - 2x - 3 by one of its factors we will get a remainder of 0. 2x 3 - 5x - 7 x - 2.

To put the divisor x 2 into the form x a use the constants negative. Sign in with Facebook. Check all that apply x - 2 is a factor of Px.

Following are the steps required for Synthetic Division of a Polynomial. Synthetic Division is an abbreviated way of dividing a polynomial by a binomial of the form x c or x c. I must say that synthetic division is the most fun way of dividing polynomials.

X 2 is a factor of Px. Polynomial Long Division Name_____ANSWERS_____ Directions. Also because of the zero remainder x 2 is the remaining factor after division.

2395 mm x2 3. Synthetic division is typically used to test whether a value is a zero or root of a polynomial. What is Synthetic Division.

P x -4 x3 5 x2 - 3 x 10. Set up the synthetic division. Dividing polynomials using synthetic division use synthetic division to divide the polynomial by the linear factor.

A synthetic division worksheet with answers pdf is a number of short questionnaires on a special topic. The division answer is. Use a zero coefficient to hold the spot during the division process.

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. Here 2x-1 2 x-12 so you can use synthetic division to divide x-12 into the polynomial to see if it is a factor which would be equivalent to 2x-1 being a factor. Find x 4 5 x 3 7 x 2 34 x 1 x 5 using synthetic division.

To set up the problem we need to set the denominator zero to find the number to put in the division box. 2 3 4 1 1xx x x32 4. In this page synthetic division worksheet we are going to see some practice questions.

Be sure to show your work. X 2 is a not factor of Px. 2x4 0x3 4x2 0x - 1.

Synthetic division is another way to divide a polynomial by the binomial x - c where c is a constant. Polynomial Long Division ANSWERS Author. The following problems deal with division of polynomials.

You divide out the coefficient of x to get a divisor of the form x-k. For example you can use synthetic division to divide by x 3 or x 6 but you cannot use synthetic division to divide by x2 2 or 3x2 x 7. X- 2 is not a factor of Px.

Use the root associated with the divisor. As was done with long division synthetic division must also fill in missing terms in the dividend. X 3 8x 3 is.
