How Do You Use Synthetic Division
If you are given say the polynomial equation y x 2 5x 6 you can factor the polynomial as y x 3x 2. Synthetic division is a method of dividing polynomials by linear expressions.

If the last number the remainder is 0 the divisor is a factor of the dividend.
How do you use synthetic division. The first is that it has to be a polynomial of degree 1. Set up the synthetic division and check to see if the remainder is zero. For this problem the answer starts with a power of 2 then a power of 1 then a power of 0 the constant.
Use synthetic division to determine whether x 1 is a zero of x 3 1. Write the polynomial being divided in descending order. 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.
Synthetic division allows you to find both the quotient and the remainder of the division. The last value in the bottom row is the remainder and is written. You get the same answer you would get if you used long division but most students find that its much much faster.
Then write only its coefficients and constant using 0 for any missing terms. You could use long division to do this but synthetic division is a shortcut method that involves only the coefficients of the terms. 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.
In this problem a 3 because you use. It may look complicated at first but you. Since you are dividing by a polynomial of degree 1 the degree of the solution will be 1 less than the degree of the dividend.
Here are some examples. The basic Mantra to perform the synthetic division process is Bring down Multiply and add multiply and add Multiply and add 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. Learn about dividing by synthetic division when the divisor is a fraction.
So you have just an x here. Were doing kind of the most basic form of synthetic division. And to do this most basic algorithm this most basic process you have to look for two things in this bottom expression.
Write the constant a of the divisor x a to the left. You dont have an x squared an x to the third an x to the fourth or. Once you know how to do synthetic division you can use the technique as a shortcut to finding factors and zeroes of polynomials.
Can you do synthetic division with a fraction. The last number would be the remainder while the previous numbers are the quotient as seen above. To do the problem using synthetic division follow this procedure.
Synthetic division is generally used however not for dividing out factors but for finding zeroes or roots of polynomials. More about this later.
