Step by step explanation please please​

Answer 1

Answer:

see the picture dear........

Answer 2

$Given \: (p-q)^{2} - 1$

$= (p-q)^{2} - 1^{2}$

/* By algebraic identity */

$\boxed{\pink{ x^{2} - y^{2} = (x+y)(x-y) }}$

$= [ (p-q)+1][(p-q)-1]$

$= ( p-q+1)(p-q-1)$

Therefore.,

$\red{ Factors \:of \: (p-q)^{2} - 1 }$

$\green { = ( p-q+1)(p-q-1) }$
