Re: algebra
Hi mukesh;
(X = 3 and Y = 4) and ( X = 4 and Y = 3 ) are two immediate answers. Those you should know.
You do not need to compute them.
These are harder: There are 6 more roots. 2 real and 4 complex.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
