Question

Solve using the identity:
(2x + 3y) (4x^2 - 6xy +9y^2)​

Answer 1

(2x+3y) (4x^2-6xy+9y^2)

8x^3+12x^2y-12x^2y-18xy^2+18xy^2-27y^3

(Cancelled)

8x^3-27y^3

.(2x-3y)^3

Use identity (a-b)^3

Then u will get the ans

see below pic for clear answer

Answer 2

Step-by-step explanation:

(2x + 3y) (4x^2 - 6xy +9y^2)

=(2x)^3 -(3y)^3

=8x^3-27y^3
