Synthetic division can only be used if youre dividing by a LINEAR factor in the form x - a. Correct answers will move you ahead incorrect answers are highlighted in red and require correction before you advance to the next input cell. Practice Problem 5 Given 8f x 4x3 10 x2 3x find f-1.
Divide using synthetic division. 1 Perform the following divisions using Synthetic Division. Use Synthetic Division to Rewrite a Polynomial.
Remember that if you have a variable without a number in front of it. Because the remainder is zero this means that x 3 is a factor and x 3 is a zero. Complete forms at right to perform your synthetic division.
It is a Super Fun way to engage students in practice and review of. SYNTHETIC DIVISION WORKSHEET Dont forget ZERO Coefficients for missing degrees Solve the binomial divisor equal to zero. For problems 4 6 use synthetic division to perform the indicated division.
Drop the first coefficient below the horizontal line. Fx dx qx. This means we can use synthetic division.
To find fk divide fx by x k. For example it works if you are dividing by x - 3 or by x 4. Whatever its product place it above the horizontal line.
Step Two Write the problem in synthetic division. Use the Remainder Theorem. Perform synthetic division to divide by a binomial in the form x - k Example.
Perform Polynomial Long Division. If the leading coefficient is not a 1 then you must divide by the leading coefficient to turn the leading coefficient into a 1. Multiply that number you drop by the number in the box.
Hit ENTER after each input to move to the next logical cell. Use Long Division to Rewrite a Polynomial. 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.
For example 3x 1 would becomeand 2x 7 would become. 2x 3 6x 2 - 17x 15 x 5 3. Long Division of Polynomials When you divide a polynomial fx by a nonzero polynomial divisor dx you get a quotient polynomial qx and a remainder polynomial rx.
Divide 7x3 1 7 x 3 1 by x2 x 2 Solution. Identify the constant in the binomial and find its opposite. Construct a polynomial from a graph and a given Factor.
Divide x3x2 x1 x 3 x 2 x 1 by x 9 x 9 Solution. Use long division to divide polynomials by other polynomials. The reduced polynomial and remainder will be provided for you when the synthetic division has been completed correctly.
X 2 5 x 6 x 1. Use synthetic division to divide polynomials by binomials of the form x k. Also because of the zero remainder x 2 is the remaining factor after division.
Using Synthetic Division to Factor a Polynomial Example 6. Add the column of numbers then put the sum directly below the. Multiply and Add Patterns If zero value is a fraction then divide all coefficients by denominator.
Y 5 - 32 y - 2 4. Synthetic division would be more difficult to perform than long division. Synthetic division can be used to evaluate a polynomial function.
