Question

Simplify (p2+q2) (p2-q2)+q4

Answer 1

Hey friend,
Here is the answer:
$( {p}^{2} + {q}^{2} )( {p}^{2} - {q}^{2} ) + {q}^{4} \\ \\ using \: the \: identity \\ (a + b)(a - b )= {(a)}^{2} - {(b)}^{2} \\ \\ = ({(p^{2} )}^{2} - {(q^{2} )}^{2} ) + {q}^{4} \\ \\ = {p}^{4} - {q}^{4} + {q}^{4} \\ \\ after \: cacncelling \: we \: get \\ \\ {p}^{4}$

Hope this helps!!!
