Question

use suitable identity to solve (5x-y)^2-(5x+y)^2​

Answer 1

Answer:

using the identity (｡◕‿◕｡)➜ a² - b² = (a+b) (a-b)

QUES - (5x - y)² - (5x +y)²

$(5x - y) ^{2} - ( {5x + y)}^{2} \\ ( {5x}^{2} ) ^{2} - ( {y}^{2} ) ^{2} \\ \longrightarrow \: {25x}^{4} - {y}^{4}$

Answer 2

Answer:

using the identity (｡◕‿◕｡)➜ a² - b² = (a+b) (a-b)

QUES - (5x - y)² - (5x +y)²

$(5x - y) ^{2} - ( {5x + y)}^{2} \\ ( {5x}^{2} ) ^{2} - ( {y}^{2} ) ^{2} \\ \longrightarrow \: {25x}^{4} - {y}^{4}$
