Question

(3x + 2y) (3x + 2y) simplify pleasee​

Answer 1

$(3x + 2y)(3x + 2y) \\ = 3x(3x + 2y) + 2y(3x + 2y) \\ = 9 {x}^{2} + 6xy + 6xy + 4 {y}^{2} \\ = 9 {x}^{2} + 12xy + 4 {y}^{2}$

Therefore, The answer is 9x²+12xy+4y²

Answer 2

Answer:

9x² + 4y² + 12 xy

Step-by-step explanation:

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

= ( 3x + 2y )²

( a + b )² = a² + b² + 2ab { Identity / formula }

Here,

a = 3x

b = 2y

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

= ( 3x + 2y )²

= ( 3x )² + ( 2y )² + 2 ( 3x ) ( 2y )

= 9x² + 4y² + 12 xy
