Question

Simplify: (1/2x²+2/3y²)²-(1/2x²-2/3y²)²​

Answer 1

Answer:

4x²/3y²

Step-by-step explanation:

let x²/2 be 'a' and 2/3y² be 'b'

There fore,

(a+b)²-(a-b)²

= a²+b²+2ab-a²-b²+2ab

So, the a² and b² are cancelled out

=2ab+2ab

=4ab

Now, put the value of a and b

= 4 multiply x²/2 multiply 2/3y²

= 4.x²/2.2/3y²

Now, simply it

Then you will get

= 4x²/3y²
