(a)(x + y) (x² − xy + y²)

(b) (x + y) (x² + xy + y²)

(c) (x + y)² (x − y)

(d) (x − y)² (x + y)

Answer 1

The given expression to be factorized is

Take common from the first two terms and from the last two terms. That is

Finally, take commonfrom the two terms. That is

So, the correct choice is (d).
