If the leading coefficient is not a 1 then you must divide by the leading coefficient to turn the leading coefficient into a 1. Step Two Write the problem in synthetic division. Divide 5x4 x28x2 5 x 4 x 2 8 x 2 by x4 x 4 Solution.

Our divisor is a linear function x-1 with leading coefficient equal to 1. Complete forms at right to perform your synthetic division. For problems 4 6 use synthetic division to perform the indicated division.

Whatever its product place it above the horizontal line. Remember that if you have a variable without a number in front of it. This means we can use synthetic division.

We are going to divide by the binomial x 3. 2x 3 6x 2 - 17x 15 x 5 3. Frac x2 5x6 x-1 x6 frac 12 x-1 x1x25x6.

Perform Polynomial Long Division. X 2 5 x 6 x 1. Drop the first coefficient below the horizontal line.

Multiply and Add Patterns If zero value is a fraction then divide all coefficients by denominator. Synthetic division can only be used if youre dividing by a LINEAR factor in the form x - a. 2 5 3 2 2 5 3 2 -2 1 5 -3 Step One Ensure that the divisor is in form and the dividend is ordered by descending degrees of.

Y 5 - 32 y - 2 4. 1 Perform the following divisions using Synthetic Division. Divide 7x3 1 7 x 3 1 by x2 x 2 Solution.

Divide x3x2 x1 x 3 x 2 x 1 by x 9 x 9 Solution. SYNTHETIC DIVISION WORKSHEET Dont forget ZERO Coefficients for missing degrees Solve the binomial divisor equal to zero. Perform synthetic division to divide by a binomial in the form x - k Example.

Synthetic division can be used to evaluate a polynomial function. Use the Remainder Theorem. Correct answers will move you ahead incorrect answers are highlighted in red and require correction before you advance to the next input cell.

16x 3 - 2 14x - 12x 2 2x 1 Show Step-by-step Solutions. For example it works if you are dividing by x - 3 or by x 4. For example 3x 1 would becomeand 2x 7 would become.
