Lesson 6 7 Part 2 Finding Zeros Using Synthetic Division The Learn the basics of using synthetic division to find zeros of polynomial equations if you are given one factor. get your pencil and paper ready for this exci. But what we're going to cover in this video is a slightly different technique, and we call it synthetic division. and synthetic division is going to seem like a little bit of voodoo in the context of this video. in the next few videos we're going to think about why it actually makes sense, why you actually get the same result as traditional. Well you could technically use 3x 3 for synthetic division because if you set that expression equal to zero, then you get 3x 3=0. then add 3 to both sides, 3x=3. after that divide both sides by 3 to get the coefficient off the x term, x=1. but for denominator expressions where you can't do what i just did, you would need to use long division. You can write the final answer in two ways. the first one is using the minus or subtraction symbol to indicate that the remainder is negative. the second one is using the symbol but attaching a negative symbol to the numerator. they mean the same thing! \left ( { – {x^5} 1} \right) \div \left ( {x 1} \right) don’t be discouraged by this.

Using synthetic division, find all zeros of 𝑓. so here, we have our function in the possibility of the zeros: two, three, or four. and we know that only one of these is one of the zeros of the function. a zero of a function will divide evenly into the function. so we need to take these numbers and use synthetic division to decide if it’s a. Synthetic division is a handy shortcut for polynomial long division problems in which we are dividing by a linear polynomial. this means that the highest power of \(x\) we are dividing by needs to be \(x^{1}\). this limits the usefulness of synthetic division, but it will serve us well for certain purposes.
