Question

Factorise the expression (2x - 3y) cube

Answer 1

Heya!!! User!!! ✌

Here's your answer friend,

****************************************************

==> (2x - 3y)³

Therefore, by using the identity

{ (a - b)³ = a³ - b³ - 3a²b + 3ab²}

==> (2x - 3y)³ = (2x)³ - (3y)³ - 3(2x)²(3y) + 3(2x)(3y)²

==> 8x³ - 27y³ - 36x²y + 54xy²

==> 8x³ - 9y( 3y² - 4x² + 6xy)

➡Is the required answer.
