First step is to write the dividend (the expression you're dividing INTO) and the divisor (the expression you're dividing BY) in the same order.BabyBlue said:I need help with another one: K (cubed)- 0K (squared)- 30K- 18-4K(squared)- 0K by 3+K

I hope I added in the zeros correctly

It was originally: K cubed- 30K-18-4K squared by 3+K

Hope I am not being a bug,

Usually, it is best to write dividend and divisor in "descending order," highest power of the variable to lowest power of the variable.

If we do this, we have

(k<SUP>3</SUP> - 4k<SUP>2</SUP> - 30k - 18) divided by (k + 3)

Ok...now, the long division process is similar to what you learned in grade school. Here's a website which "walks you through" the process. http://www.purplemath.com/modules/polydiv2.htm

Study the website, and see what you can do with your problem. If you still have trouble, please repost showing all of the work you have done.

Now, about the problem I am having. You said you should arrange it in the order of the divisor. So, the long division problem: (Kcubed-30K-18-4Ksquared) divided by (3+K)

So I would need to do this:

(0K-Ok sqaured- K cubed- 30K- 18- 4K squared)?

I just need a little help on the set up.

Thanks,

It is: K squared-7K-9

fraction positive 9 over 3+K

I guess I was just confused.

From now on I know adding zeros is not always the answer.

If someone else ever needs help with dividing polynomials they should go to:
