Question

find the product of (3x + 2y)(9x^2 - 6xy + 4y^2)​

Answer 1

Step-by-step explanation:

3x(9x²-6xy+4y2)+2y(9x²-6xy+4y²)

=27x³-18x²y+12xy²+18x²y-12xy²+8y³

=27x³+8y³

OK friend this is urs answer

Answer 2

Step-by-step explanation:

$\: \: \: \: (3x + 2y)(9 {x}^{2} - 6xy + 4 {y}^{2} ) \\ = > (3x + 2y)(( {3x})^{2} - 3x.2y + ( {2y})^{2} ) \\ = > { \: (3x})^{3} + ( {2y})^{3} \\ = > 27 {x}^{3} + 8 {y}^{3}$

Using formula:-

a^3+b^3= (a+b)(a^2-ab+b^2)
