Question

[3x/4+2y/9]² expand​

Answer 1

Answer:

27 X square + 8 y square + 432 x y

Answer 2

Answer:

9x²/16 + xy/3 + 4y²/81

Step-by-step explanation:

Using Suitable Identities:-

[a+b]²=a²+2ab+b²

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

=[9x²/16]+[12xy/36]+[4y²/81]

=9x²/16 + xy/3 + 4y²/81
