Using associate property to simplify multiplication. Write the coefficients of the dividend to the right. I think youve probably heard the word divide before where someone tells you to divide something up divide the money between you and your brother or between you and your buddy and it essentially means to cut up something so let me write down the word divide divided so if we had lets say that I have four quarters let me see do my best to draw the quarters if I have four quarters just like that.

X 4 x 3 x 2 x 1 x 0 5 1 5 7 34 1. To set up the problem we need to set the denominator zero to find the number to put in the division box. This latter form can be more useful for many problems that involve polynomials.

Then the numerator is written in descending order and if any terms are missing we need to. For example x²-3x5x-1 can be written as x-23x-1. MIT grad shows how to do synthetic division a shortcut for long division.

Write the problem in a division-like format. Divide x squared minus 3x plus 2 divided by X minus 2 so were going to divide this into that and we could do this really the same way that you first learn long division so we have X minus 2 being divided into x squared minus 3x plus 2 another way we could have written the same exact.
