Answer 1

Answer:

4x² + 1 - 4x is the answer

Step-by-step explanation:

(2x-1)²

by identity (a-b)² = a² + b² -2ab

(2x-1) = (2x)² + (1)² - 2(2x)(1)

= 4x² + 1 - 4x

HOPE IT HELPS YOU!!!

Answer 2

Answer:

4x²+1-4x

Step-by-step explanation:

Question:-

(2x-1)²

Solution:-

As we know that we use this identity to solve this question i.e. :-

(a-b)²=a²+b²+2ab

Now,

Here a=2x

b=1

So our equation comes i.e. :-

2x²+1²-2(2x+1)

So lets solve this equation:-

2x²+1²-2(2x+1)

4x²+1-4x-2

4x²+1-4x

So our answer is:- 4x²+1-4x
