Could someone help me to simplify this expression:
You can start by factoring out n
I forgot to mention that it should be in the form of:
Well, n is a common factor so can you start yourself?
After that, it'll be a bit harder to find factors but still doable (by finding zeroes of the polynomial!).
Try factoring out n yourself ?
thanks for the fast reply!
I have tried to get the roots (the zeros). After taking n as a common factor we have:
" 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
If a is a zero, then you can factor out (x-a)
Try adding up all coëfficiënts of the even powers in x and the ones of the odd powers in x, if these 2 are the same then -1 is a zero and thus, (x+1) a factor.
Thanks TD for your very fast replies
By taking the roots i get the simplification:
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......
Then, you should be able to divide your original polynomial by n(n+1) and see what's left.
By the way, "strange" is irrational.
I solved it!! :rofl:
if you multiply those irrational numbers you get a rational value!!!
The simplified answer is
Separate names with a comma.
