Vedclass · Answer

(A) The given expression is $\left(y^{2}+\frac{3}{2}\right)\left(y^{2}-\frac{3}{2}\right)$.Using the algebraic identity $(a+b)(a-b) = a^{2}-b^{2}$,where $a = y^{2}$ and $b = \frac{3}{2}$,we get:$\left(y^{2}+\frac{3}{2}\right)\left(y^{2}-\frac{3}{2}\right) = (y^{2})^{2} - \left(\frac{3}{2}\right)^{2}$$= y^{4} - \frac{9}{4}$

Use suitable identities to find the product: $\left(y^{2}+\frac{3}{2}\right)\left(y^{2}-\frac{3}{2}\right)$
