9p^2 - 6 = 642;  / + 6 ;
9p^2 = 648;       / ÷9 ;
p^2 = 72 ;
p = + [tex] \sqrt{72} or - \sqrt{72} [/tex];
Finally, p = +6[tex] \sqrt{2} [/tex] or p = -6[tex] \sqrt{2} .[/tex]

9p^2-6=642
⇒ 9p^2= 642+6
⇒ 9p^2= 648
⇒ p^2= 648/9
⇒ p^2= 72
⇒ p= 6√(2) or p= -6√(2)

The final answer is p= 6√(2) or p= -6√(2)~
