Answer» Given ((3x/4) + (2y/9))² According to the identity (a + b)²=a²+2ab+b²we have to expand the given expression, ((3x/4) + (2y/9))²= (3x/4)²+2 (3x/4) (2y/9)+ (2y/9)² ((3x/4) + (2y/9))²= 9x²/16+ (1/3) xy + (4y ²/81)

Answer»

Given ((3x/4) + (2y/9))²

According to the identity (a + b)²=a²+2ab+b²we have to expand the given expression,

((3x/4) + (2y/9))²= (3x/4)²+2 (3x/4) (2y/9)+ (2y/9)²

((3x/4) + (2y/9))²= 9x²/16+ (1/3) xy + (4y ²/81)
