Hi!(adsbygoogle = window.adsbygoogle || []).push({});

This is my first post at this forum. At the look of it I think i will be spending a lot of time here. I´ve have a problem that i need help with. Me and my boyfriend started a discussion yeasterday who was the smartest of us. So we gave each other a assignment. Mine was:

Solve the equation

| 1 1 1 1|

| x 2 3 4|

| x^2 4 9 16| = 0

| x^3 8 27 64|

I´ve have thought out that i need to use linear algebra to solve this. This is were my problem kick in. I´ve have just read moderate linaer algebra. So please can you help me. Don´t want to be the dumb one We didn´t say how we should solve it...

Thanks in advance! /X Sandra
