[tex](x+y)^4=x^4+y^4[/tex]
We know this is true if x and/or y = 0, but what other possibilities are there?
I solved for (x+y)^2=x^2+y^2, which has x=-y as a possibility.
The solution isn't necessary, a couple tips should lead me in the right direction.
I broke it down in several ways, but a hint for something to look for would be great. I happen to always be stuck with something along the line like...
STUFF+x^2y^2
I can get the stuff area to equal to zero, but because the are both odd or even numbers that are equal I am always stuff with the odd one at the end.
I lost my paper that shows what STUFF is (stupid I know), but I'll work out a second time and maybe then I'll find a solution.
Any advice would be great.
Thanks.
