ANSWER:

The factors of

SOLUTION:

Given, polynomial is  

This is an polynomial in two variables with degree 4

So the given polynomial will have 4 factors.

We need to factorise the given polynomial.

Now,

[writing terms with y as one part and remaining as another part]\

Taking the common terms out of brackets.

Taking as common

Hence the factors  of
