Question

Using appropriate identities,find products(2/3y-1)(2/3y-1)​

Answer 1

Answer:

4/9y² + 4/3y + 1

Step-by-step explanation:

As both are same, we can simplify it to (2/3y-1)²

Now, we can use the identity of ( a - b )² = a² - 2ab + b², where a = 2/3y & b = 1.

Therefore, it would be (2/3y)² + 2 × 2/3y ×1 + (1)²

= 4/9y² + 4/3y + 1

Answer 2

Answer:

Answer. Now, we can use the identity of ( a - b )² = a² - 2ab + b², where a = 2/3y & b= 1
