$x^2 + xy + y^3 \quad और \quad x^3 - y^3 \quad का \quad LCM \quad निकालिए$

This translates to:

"Find the LCM (Least Common Multiple) of $x^2 + xy + y^3$ and $x^3 - y^3$."

Solution:

1. Expression 1: $x^2 + xy + y^3$ This expression does not follow any standard factorization rules, so we leave it as it is.

2. Expression 2: $x^3 - y^3$ This is a difference of cubes, and it can be factorized as: $x^3 - y^3 = (x - y)(x^2 + xy + y^2)$

Finding the LCM:

• The first expression $x^2 + xy + y^3$ does not share a direct factorization with the second expression.
• The second expression $x^3 - y^3$ has the factorization $(x - y)(x^2 + xy + y^2)$, but this does not directly include $y^3$, so no common factor exists.

The LCM will be the product of the two expressions, as they do not share a common factor: $LCM = (x^2 + xy + y^3)(x - y)(x^2 + xy + y^2)$

Thus, the LCM is: $LCM = (x^2 + xy + y^3)(x - y)(x^2 + xy + y^2)$
