Question

25x² - 10x + 1 - 49y².​

Answer 1

Answer:

Step-by-step explanation:

25x² - 10x + 1 -36y²  

(25x² - 10x + 1) -36y² =  

(5x - 1)² - 36y² =  

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

Answer 2

=(25x²-10x+1)-49y²

=(5x-1)²-(7y)² [ using identity(a+b)²=a²-2ab+b²]

(5x-1+7y)(5x-1-7y)

[using identity a²-b²=(a+b)(a-b)]
