Use polynomial long division to divide 25x^3 + 40x^2 + 25x + 10 by -5x^2 – 3x – 2
this is what I got for my answer
-9 n^6+n^5-2 (4 n^6-7 n^5+5)+25 x^3+40 x^2-2/x^2+22 x-8
wow that looks off
Tough to show online. The answer is -5x - 5.
but how did they get it was what I was wondering or is it to hard?

yeah it is to hard to show online I just looked at purplemath.com ans seen
http://www.purplemath.com/modules/polydiv2.htm to be precise
In the first step we need to find something times -5x^2 to equal 25x^3. That something is -5x. I would go to www.khanacademy.org and look at the long division video ...
