Question

EXPAND
(3x + 2y) (3x + 2y) (3x + 2y)​

Answer 1

Answer:

(3x + 2y)(3x + 2y)(3x + 2y)

=(3x+2y)^3

=3x^3+2y^3+3(3x*2y)

=27x^3 +8y^3+18xy

hope this will help you

Answer 2

Answer:

above equation =(3x + 2y)³

identity used - (a+b)³ = a³+b³ +3ab(a+b)

27x³ + 8y³ + 3*2y*3x(3x + 2y)

= 27x³ + 8y³ + 18xy(3x + 2y)

=27x³ + 8y³ + 54x²y + 36y²x
