Question 57 (b)

Add the following expression:

$x^{3} - x^{2} y - x y^{2} - y^{3}$ and $x^{3} - 2 x^{2} y + 3 x y^{2} + 4 y$

Open in App

Solution

We have, $x^{3} - x^{2} y - x y^{2} - y^{3}$ and $x^{3} - 2 x^{2} y + 3 x y^{2} + 4 y$
On combining the like terms,
$= x^{3} + x^{3} - x^{2} y - 2 x^{2} y - x y^{2} + 3 x y^{2} - y^{3} + 4 y = 2 x^{3} - 3 x^{2} y + 2 x y^{2} - y^{3} + 4 y$
