Question

use identity (y^2+3/2) (y^2-3/2)

Answer 1

hey mate

(y^2 + 3/2) (y^2-3/2)

it is in the form of (a+b)(a-b)= (a)^2-(b)^2

so answer will (y^2)^2 - (3/2)2 or you can write (y)^4 - (9/4)

Answer 2

Hey dear !!


here is yr answer....


=> (y²+3/2) (y²-3/2)



it is in the form of -------

(a+b) (a-b) =a²-b²


a=y² , b=3/2


=> (y²)² - (3/2)²

=> y^4 -9/4


Hope it hlpzz....
