I have some shitty easy exercice which i did right on my test but i can't figure out anymore how :D
(X^6 -1 )
------------
x+1
it has to be :
(X^5)-(X^4*1)+(X^3*1^2)-(X^2*1^3)+(X*1^4)-(1^5)
which gives : x^5 - x^4 + x^3 + x - 1
WTF :D it's so easy i don't know it anymore , what's the trick
(X^6 -1 )
------------
x+1
it has to be :
(X^5)-(X^4*1)+(X^3*1^2)-(X^2*1^3)+(X*1^4)-(1^5)
which gives : x^5 - x^4 + x^3 + x - 1
WTF :D it's so easy i don't know it anymore , what's the trick
ok no offence: D
it's quite thought provoking to wonder if number/math has a necessary existence or if it is just a human construct
had it in school but it's like 13 years away :P ... can´t remember shit and i always sucked at maths
(X^5)-(X^4*1)+(X^3*1^2)-(X^2*1^3)+(X*1^4)-(1^5)
hier zie ge duidelijk da de waarde in exponent van x daalt van 5,4,3,2,1 en da de waarde van exponent van "1" stijgt van 1,2,3,4,5,
snap je
als dees is wa ge bedoelt
You know that -1 must be a zero point, as you know that answer is a polynomial, so:
1 0 0 0 0 0 1
-1 1 -1 1 -1 1 -1 0
so:
x6-1=(x+1)(x5-x4+x3-x2+x-1)
Dunno how you get yours 1^sth but it's teh same :P
This site is quite nice to learn it. Enter ur task and it will be explained step by step.
