Jack Ryan:pls tel us how u did it.hope u didnt use a software or calculator. |
Re: Hardest Maths Question by JackRyan(m): 12:34pm On Nov 13, 2010 |
No I didn't use any software or calculator. I solved it using a combination of substitution method, elimination method, binomial theorem and simultaneous equation method among others. And then I played with the equations I got some before I got what I was looking for. The key to solving this problem is to reduce all that bullshit to one equation in one variable and solving for that variable. When you finally get the equation in one variable, its going to be a polynomial to the order of 3, so you get 3 roots. If you are sharp you will notice that the three roots you get are going to be the same for the other two polynomials in the other two variables, so the three roots are the three variables. |

Yeah, just search for ''my school comm'' (type it without space) on facebook and LIKE it, you'll get the latest gist about our tertiary schools in Nigeria and/or otherwise concerning admissions and all other educational stuffs. I found it useful and I don't want to be selfish; therefore, that's why I'm sharing this. @all, JUST HAVE A LOOK AT THE FB PAGE AND YOU'LL BE NATURAL FORCED TO PRESS THE 'LIKE' BUTTON! Enjoy! |

Re: Hardest Maths Question by tobiope: 6:38pm On Apr 26, 2015 |
have solve it , but the questions is like this, x + y + z= 1 x^2 + y^2 + z^2=35 , x^3 + y^3 + z^3 =97 . |
Re: Hardest Maths Question by thankyouJesus(m): 10:07pm On Apr 26, 2015 |
Rasulullah:here we go x + y + z = 1 x + y = 1 - z x^2 + y^2 + z^2 = 34 x^2 + y^2 = 34 - z^2 (x + y)^2 - 2xy = 34 - z^2 from (1) (1 - z)^2 - 2xy = 34 - z^2 (1 - 2z + z^2) - 2xy = 34 - z^2 2z^2 - 2z - 33 = 2xy xy = (2z^2 - 2z - 33)/2 from 3 x^3 + y^3 + z^3 = 97 (x+y)^3 - 3x^2y - 3xy^2 = 97 - z^3 (x+y)^3 - 3xy(x+y) = 97 - z^3 I believe you can continue from here, all you do is substitute. |
Re: Hardest Maths Question by tobiope: 10:54pm On Apr 26, 2015 |
have already solve it , i got x=-3 or 5 ,y=5 or -3 and z= -1 twice . |

Very cheap question.
I can play with it. |
Re: Hardest Maths Question by usmanktg2(m): 6:17pm On Apr 30, 2017 |
I can't believe I posted this question 7 years ago under my former username. I can now clearly see how cheap this question is. Refer to Advanced Mathematics books such as Backhouse & HK Dass. They have amazing answers to this. Thank you. |
