Math problem unsolvable, and tomorrow's mah exam.
I posted this a while ago, and it came under some other users name, so deleted it and now :
| a^2 a^2-(b-c)^2 bc |
| b^2 b^2-(c-a)^2 ca |
| c^2 c^2-(a-b)^2 ab|
It has be solved without expanding and with matrices.
Yelp Yelp, exam tomorrow !
listen up buddy, aint go no time to give a complete solution now.
I'm sure you know some of it, so i'll just tell ya in text.
btw, this is the wrong website to post math problems.
The solution :
From row2, make it two matrices.
The first matrix should go off because of two similiar rows.
Now the second one looks like this :
| a^2 -(b-c)^2 bc |
| b^2 -(c-a)^2 ca |
| c^2 -(a-b)^2 ab |
Apply C2 -> C1+C2+ 2* C3
Now row two has similiar values, expand through C12 and solve.
This is most probably right, considering what i know.

Edit : i posted the solution once, thought it was wrong, here is a small edit.
Edit 1 : Assuming a^2, means a square, and C1 means column1 etc.
lol you make it sound very simple
Thank you anyway.
Determinants normally dont post much of a problem.
Keep in mind, that :
1. Look at the To Prove, and try to make it simpler by going behind 2 steps.
2. Look at the given equation and try to go ahead 2-3 steps.
That normally solves it all.
Otherwise, just keep simplifying it as much as ya can, and try different permutations, and you shall be able to solve it.
