## Is a polynomial a power series?

A power series is basically an infinite degree polynomial that represents some function. Since we know a lot more about polynomial functions than arbitrary functions, this allows us to readily differentiate, integrate, and approximate some functions using power series.

## How do you divide polynomials with exponents?

To simplify each term, divide the coefficients and apply the quotient rule for exponents. When dividing a polynomial by another polynomial, apply the division algorithm. To check the answer after dividing, multiply the divisor by the quotient and add the remainder (if necessary) to obtain the dividend.

**Can we multiply two power series?**

In Note, we state the main result regarding multiplying power series, showing that if ∞∑n=0cnxn and ∞∑n=0dnxn converge on a common interval I, then we can multiply the series in this way, and the resulting series also converges on the interval I.

**What is the difference between power series and polynomial?**

In short terms polynomials are a kind of (regular and smooth) functions, whereas power series can converges (in a given domain) to others functions or not converge at all.

### Why power series is not the polynomial?

A power series is not necessarily a polynomial unless from some point on all the coefficients are zero. A polynomial can be considered a power series whose coefficients are zero from some point on.

### How do you divide a polynomial?

Dividing Polynomials Using Long Division

- Divide the first term of the dividend (4×2) by the first term of the divisor (x), and put that as the first term in the quotient (4x).
- Multiply the divisor by that answer, place the product (4×2 – 12x) below the dividend.
- Subtract to create a new polynomial (7x – 21).

**Can you divide a polynomial by a linear term?**

Luckily there is something out there called synthetic division that works wonderfully for these kinds of problems. In order to use synthetic division we must be dividing a polynomial by a linear term in the form x −r x − r. If we aren’t then it won’t work. Let’s redo the previous problem with synthetic division to see how it works.

**Can you use synthetic division to divide polynomials?**

In order to use synthetic division we must be dividing a polynomial by a linear term in the form x −r x − r. If we aren’t then it won’t work. Let’s redo the previous problem with synthetic division to see how it works. Example 2 Use synthetic division to divide 5×3−x2 +6 5 x 3 − x 2 + 6 by x−4 x − 4 .

#### Why are my dividing polynomials not working on my computer?

If your device is not in landscape mode many of the equations will run off the side of your device (should be able to scroll to see them) and some of the menu items will be cut off due to the narrow screen width. In this section we’re going to take a brief look at dividing polynomials.

#### Which is the correct notation for dividing a polynomial?

There are many different notations for doing this. We’ll be using the following notation. The numbers to the right of the vertical bar are the coefficients of the terms in the polynomial written in order of decreasing exponent. Also notice that any missing terms are acknowledged with a coefficient of zero.
