Answer:

25x²-2x+1/25

= 625x²-50x+1 (taking LCM as 25)

= 625x²-25x-25x+1

= 25x(25-1)-1(25x-1)

= (25x-1) (25x-1)

This is your required answer

or we can do it in another way....

25x²-2x+1/25

(5x)²-2×5x×1/5+(1/5)²

This is in the form of (a²+b²-2ab)

Hence the required answer is....

(5x-1/5)²

hope it helps...

sakshisingh4815: This is wrong. I have to solve this question by the formula a^2 - 2ab + b^2 = (a-b)^2
