$\huge\boxed{\underline{\underline{\green{\tt Solution}}}} </p><p>$

We are aware of the identity that

${(x - y)}^{2} = {x}^{2} + {y}^{2} - 2xy$

Using the above mentioned Identity we get

${( {p}^{2} - {q}^{2} )}^{2} </strong></p><p></p><p><strong>= {( {p}^{2} )}^{2} + {( {q}^{2} )}^{2} - 2 \times {p}^{2} \times {q}^{2}$

= $</strong><strong>{p}^{4} + {q}^{4} - 2 {p}^{2} {q}^{2}$
