Question

Find the following product using appropriate Identity.
i)(y-1) (y-1)=(y-1)²
(x-y)²=x²-2xy+y²
(y-1)²=​

Answer 1

Answer:

Here's your answer

Step-by-step explanation:

We need to find value of (y−1)(y−1)

Thus y−1)(y−1) =(y−1)2

Using identity  (x−y)2=x2−2xy+y2

Therefore, (y−1)2

=(y)2−2×y×1+(1)2

=y2−2y+1

Hope you understand.
