Hey guys this question was given in question 1,essay part, 2009 FINAL COWBELL NASSMAC COMPETITION LAGOS, please we seriously need help on it.(the numbers after the letters are powers)
x+y+z=1
x2+y2+z2=34
x3+y3+z3=97

A

Raise to power what,is it power 2. I mean d numbers attached to alphabets

Xd

^^ answer it now, mr UNN

@op, what is the question or what are we to do? Are we to find the value of the variables?

You are required to find x, y, z

Will simultaneous equation or matrix solve the question?

nither simultaenous nor matrix can, i fink it has to do with smtn higher

Matrix wil not solve it because all d coefficients are zero

I'll get back here in d evening cos presently am in d vehicle 4rm ibadan to lag. When i get home,i'll try it

Safe journey

I think it wil not b solve using substitution method, rather using coeffitients does not come here

Complex solutions

Complex solutions

No mathematician in the house?

D question wil be solved using a subtitution method,its a simultaneous equation with 3 variables.

if u re gonna use substitution its gona be very complex nd out of control cos i tried it, anyway still du wat u cn cos i really wnt tu know the answer

Hold on guys.i tink i shuld b able to solve it.

Guys,i don't think d question is right because its a simultaneous linear equation with three unknowns and the step i took is take a pair of d equation and eliminate one of d variables and later take another pair ,then bring together what u got 4rm d first and second pairing and then solve it like simultaneous equation. Then finally substitute these values in one of d origina equation to obtain d third value. But i've been solving other question like this but in this one now the varibles are giving me zero. Mayb its not correct.

D question is 100% correct

The 3rd equation is probably wrong.

I wonder why dey gave us dat question last year, at 14 yrs

I hv d answers, but my problems are d steps and solutions, I GOT D ANSWER FROM MICROSOFT MATHS, but i think it uses graphical method with 3d, I NEED UR PERMISSIONS TO PASTE D ANSWER, but help me take to a lecturer or prof

Mehn dis work na die.but am vry sure its GUSSIAN rule that one can use 2 solve it,i.e makn one of d variables subjet of formla in one of d 3 equations nd pairn 2 of d oda 3 equations,substn d value of the changd subject of formla in those equatns then solvin simultaneously.afta dat replace d values of the variables in any of d 3 initial equatns to get ur answa.but as pa dis work d fuda u go d more complicatd d solutn.and dis was d first tin i did today on d bed,now am avn serious headache.

Oga maths oo

Omo, i tried using 3X3 matrix, but my answer wasn't correct! I don't know how to answer this question, i also tried substitution method but the question just became more complex.

U cant use matrix because 4rm what I noe u can only use matrix to solve linear simultaneous equatns but dis one is not linear.

dont provide the answer yet because to every pro there is always a solution

@topic im almost there

[h3]I am alwayz saying dis, MATRIX wil not solve dis because d coefficients are all d same(=1) [/h3]

Mehn dis work na die.but am vry sure its GUSSIAN rule that one can use 2 solve it,i.e makn one of d variables subjet of formla in one of d 3 equations nd pairn 2 of d oda 3 equations,substn d value of the changd subject of formla in those equatns then solvin simultaneously.afta dat replace d values of the variables in any of d 3 initial equatns to get your answa.but as pa dis work d fuda u go d more complicatd d solutn.and dis was d first tin i did today on d bed,now am avn serious headache.

stories work am guy

^ why are you looking for trouble here and there?
