Question

find the product of using appropriate identities( y²+3/5)(y²-3/5)​

Answer 1

Step-by-step explanation:

= (y² + 3/5)(y² - 3/5)

= y²(y² - 3/5) + 3/5(y² - 3/5)

= y⁴ - 3/5y² + 3/5y² - 9/25

= y⁴ - 9/25

Answer 2

Answer:

= y⁴ - 9/25

Step-by-step explanation:

= y²(y² - 3/5) + 3/5(y² - 3/5)

= y⁴ - 3/5y² + 3/5y² - 9/25

== y²(y² - 3/5) + 3/5(y² - 3/5)

= y⁴ -9/25
