Now look at this practice problem.
Examples of synthetic division problems with answers. Hit ENTER after each input to move to the next logical cell. This set-up allows us to complete the division problem 2x4 6x3 23x2 16x 5 x 5. Write the coefficients in an upside down division sign.
Use synthetic division to divide. The first power is one less than the highest power of the polynomial that was being divided. 22x2 x 10 x 7.
Perform synthetic division to divide by a binomial in the form x - k Example. 3x4 10 x3 24 x2 6xF. Remember that if you have a variable without a number in front of it the coefficient is 1.
For example 3x 1 would become and 2x 7 would become. Examples 1 2 3 4. X4 x3 14 x2 16 x 32 C.
The reduced polynomial and remainder will be provided for you when the synthetic division has been completed correctly. This is the same as writing the dividend in descending order. This question is asking me in effect to convert an improper polynomial fraction into a polynomial mixed number.
So the quotient is. So if the remainder comes out to be 0 when you apply synthetic division then x - c is a factor of f x. C 2.
2x 3 6x 2 29 x 3 2. Lets use synthetic division to work out this problem. Multiply that number you drop by the number in the box.
2x 3 4x 2 - 2x - 3. X2 5x 5x3 x4 5 x 9. That means using x 2 so a 2.
25x3 6x2 3x 11 x 8. Divide the polynomial x 4 5x 3 2x 2 28x 12 by the first degree binomial x 3. 2 2 4 3 2 1 x x x x x x For Problems 12 16 use synthetic division and the Remainder Theorem to find the indicated function value.
X3 4x2 5x 2 B. Use synthetic division to divide 27 polynomials by binomials 17 are ready to go the last 10 need to be simplified before they can use synthetic division to find the answer to the jokeStep-by-step answer key is includedGreat for sub plans additional practice or remote learning. Identify the coefficients and constants.
Use Synthetic Division to check each zero. The Remainder Theorem states that f c the remainder. Put the opposite of the number from the divisor to the left of the division symbol.
For Problems 6 11 divide using synthetic division. Correct answers will move you ahead incorrect answers are highlighted in red and require correction before you advance to the next input cell. Finally construct a horizontal line just below the coefficients of the dividend.
The process of Synthetic Division uses these relationships as a shortcut to finding the answer. Divide using synthetic division. 2x 3 6x 2 - 17x 15 x 5 3.
If the leading coefficient is not a 1 then you must divide by the leading coefficient to turn the leading coefficient into a 1. Suppose the previous division was. 4 4 256 x x 11.
Divide 5 x4 6 x3 9 x2 7 x 6 by x 2 using the synthetic method. Drop the first coefficient below the horizontal line. For example 4x 1 and 4x 9 would be x ¼ and x 94 respectively.
Y 5 - 32 y - 2. The division answer is. If synthetic division will not work then you must.
4x3 9x2 6x 1 E. Divide by synthetic division. 2x 3 6x 2 - 17x 15 x 5 3.
Divide using synthetic division. Take your leading coefficient and bring it down below the division. 3 x3 - x - 7 x - 2 Step 1 If the divisor is x - n write n and then draw a vertical line to the right of it.
2 7 510 312 x x x x 10. To perform polynomial synthetic division here are the steps. C - 2 c 2 inside the box.
Please watch the following videos for more examples of Synthetic Division. So the quotient is. Express the dividend in standard form.
Write the answer in the form q x r x d x. Divide 3x 3 2x 2 3x 4 by x 3 using synthetic division. If the leading coefficient is not 1 then we need to divide by the leading coefficient to turn the leading coefficient into 1.
2x 3 6x 2 29 x 4 2. For example you can use synthetic division to divide by x 3 or x 6 but you cannot use synthetic division to divide by x 2 2 or 3x 2 x 7. Section 2 When you reach a quadratic equation perform regular factoring or Quadratic Formula.
3 x53 9x2 4x 12. 5x3 29 x2 19 x 5 D. You can use synthetic division to help you with this type of problem.
Set the divisor to zero to find the number to put in the division box. To put the divisor x 2 into the form x a use the constants negative. Divide using synthetic division.
For example we can use synthetic division method to divide a polynomial of 2 degrees by x a or x a but you cannot use this method to divide by x 2 3 or 5x 2 x 7. Y 5 - 32 y - 2 4. The set-up for a Synthetic Division problem is shown below.
16x 3 - 2 14x - 12x 2 2x 1 Show Step-by-step Solutions.
