Simplify a expression

Hi,
Could someone help me to simplify this expression:

6n^5+15n^4+10n^3-n

Thanks,

 

I forgot to mention that it should be in the form of:
n(n+1)(.........

thanks

 

thanks for the fast reply!

I have tried to get the roots (the zeros). After taking n as a common factor we have:
n(6n^4+15n^3+10n^2-1)

" 6n^4+15n^3+10n^2-1" has 4 roots and two of them are "strange" (dont know a better word). what i mean by strange is that one is unable to write them as 1/2, 1/3 or x/y.

the value of the root is: -1.263763........
the other root is: 0,263763........

does anyone know how to deal with these kind of problems

 

Thanks TD for your very fast replies

By taking the roots i get the simplification:

(x+1.263763....)(x+1)(2x+1)(x-0,263763......)

I did not understand what u mean (i have the same powers for all x (=1), or?)
However, can i by any method cancel the 0.263763......

 

I solved it!! :rofl:

if you multiply those irrational numbers you get a rational value!!!
The simplified answer is

x(x+1)(2x+1)(3x^2+3x-1)
