Answer 1

Using X^2 - Y^2 = (X-Y)(X+Y)

WE GET ( C+ 3B-5Y )( C+3B+ 5Y )

Answer 2

Answer:

Question :-

➠ (c + 3b)² - 25y²

Formula used :-

➪ a² - b²

➭ (a + b) (a - b)

Answer :-

➠ (c + 3b)² - 25y²

➻ (c + 3b)² - (5y)²

➻ (c + 3b + 5y) (c + 3b - 5y)

∴ The value of (c + 3b)² - 25y² is (c + 3b + 5y) (c + 3b - 5y)
