Question

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




i need ASAP​

Answer 1

Answer:

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

Using identity (a+b)(a-b)=a^2-b^2

Here, a= y^2. and b=3/2

Step-by-step explanation:

So, answer is y^2^2-(3/2)^2

=y^4-9/4

Answer 2

Answer:

(y2+23)(y2−23)

This is in the form of (a+b)(a−b)

=a2−b2⇒(y2+23)(y2−23)=(y2)

2−(23)2⇒(y2+23)(y2− 23)

=y4− 49
