# Simplify: X2(X − Y) Y2(X + 2y) - Mathematics

Simplify:
x2(x − y) y2(x + 2y)

#### Solution

To simplify, we will proceed as follows:

$x^2 \left( x - y \right) y^2 \left( x + 2y \right)$

$= \left[ x^2 \left( x - y \right) \right]\left[ y^2 \left( x + 2y \right) \right]$

$= \left( x^3 - x^2 y \right)\left( x y^2 + 2 y^3 \right)$

$= x^3 \left( x y^2 + 2 y^3 \right) - x^2 y\left( x y^2 + 2 y^3 \right)$

$= x^4 y^2 + 2 x^3 y^3 - \left[ x^3 y^3 + 2 x^2 y^4 \right]$

$= x^4 y^2 + 2 x^3 y^3 - x^3 y^3 - 2 x^2 y^4$

$= x^4 y^2 + x^3 y^3 - 2 x^2 y^4$

Thus, the answer is $x^4 y^2 + x^3 y^3 - 2 x^2 y^4$.
