the largest interval in which  x¹² - x⁹ + x⁴ - x +1 >0 is

isnt it  ?

yes sandeepramesh i think that it will be  because x¹² will be dominant over lower powers of x for ⁺  and for^- there will be no problem as it all will be +ve.

hope u got it.

animal, cant you talk as mathematical expressions where you need to talk abt it?

And what you said is wrong! What about for 0<x<1?

Similar sums have already been solved! Search for them!

hey man atleast I gave the reason but u didnt had that much matter to write and i can explain for 0<x<1.

as for 0<x<1 the value of x¹²-x⁹+x⁴-x cant be less than -1 and if u dont beleive me put any value and check it !

sorry to have angered you animal, but i was just pointing a flaw in your statement thats all!

Also, as i said, we should have a better search option, such a problem has been posted many times and i have provided many solutions and so has bhattji and sboosy!
