idk how to type exponets on a computer so i will put them all in ()"s
19y(5) + 3y(2) - 2y HELP PLEASE!! lol its homework so if someone could awnser me before 9:30 it would be awesome!! k! Thanks!

The simplest way to show exponents is to use the ^ key. You have 19y^5- 3y^2- 2y. Now, what is the question? Factor something out of it? There is at least one "y" in every term so you can factor out a y. That leaves just "2" for the last term and 19 is not divisible by 2 so "y" is the only thing you can factor out if you want integer coefficients. But if you will allow fractions, you can "factor" out just about any number you want.

You can show exponents this way 19y^5, where 5 is the exponent.

You need to read the guideline Read Before Posting.

Since you have not, we do not give answers; we give help. To do that, we need to know what you have tried so we can see where you are stuck.

\(\displaystyle 19y^5 + 3y^2 - 2y\) involves 3 specified numbers, namely 19, 5, and - 2, and one unspecified number, namely y.

Is there any common factor among \(\displaystyle 19,\ 3,\ and\ 2\)? If so, what is it?

Is there any common factor among \(\displaystyle y^5,\ y^2,\ and\ y\)? If so, what is it?
