The factor of the given equation is [tex](9p - 8q)^2[/tex].
Given that,
Based on the above information, the calculation is as follows:
[tex]= 81p^2 -144pq + 64q ^2\\\\= (9p - 8q) (9p - 8q)\\\\= (9p - 8q)^2[/tex]
Therefore we can conclude that The factor of the given equation is [tex](9p - 8q)^2[/tex].
