AcademicMathematicsNCERTClass 8

Given:

$x^2 (x + 2y) (x - 3y)$

To do:

We have to simplify the given expression.

Solution:

$x^2 (x + 2y) (x - 3y)= x^2 [x (x - 3y) + 2y (x - 3y)]$

$= x^2 [x^2 - 3xy + 2xy - 6y^2]$

$= x^2 (x^2 - xy - 6y^2)$

$= x^2(x^2) - x^2(xy) - x^2(6y^2)$

$= x^4 - x^3y - 6x^2y^2$
