Question

25x² - 10x + 1 - 36y²​

Answer 1

Answer:

(5x - 1 - 6y)(5x - 1 + 6y)

Step-by-step explanation:

25x² - 10x + 1 - 36y²​

25x² - 10x + 1 -36y²  

(25x² - 10x + 1) -36y² =  

(5x - 1)² - 36y² =  

(5x - 1 - 6y)(5x - 1 + 6y)

Answer 2

25x² - 10x + 1

= (5x)² - 2*5x*1 + (1)²

= (5x - 1)²

25x² - 10x + 1 -36y²

= (5x - 1)² - 36y²

= (5x-1)² - (6y)²

= (5x-1+6y)(5x-1-6y)

Here I used the equations

(a-b)² = a²-2ab+b²      and

a²-b² = (a+b)(a-b)
