my pleasure
how about this?
(a-5)^2=81
\[(a-b)^2 = a^2 + b^2 - 2ab \]
now using this identity we have \[(a-5)^2 = a^2 + 5^2 - 2(a)(5) \]

\[a^2 + 25 - 10a\]
\[(a-5)^2=81\] \[a-5=9\] or \[a-5=-9\] \[a=14\] or \[a=-4\]
this was how to expand it but now how to simplify it is following
ok
\[(a-5)^2 = 81 \]

how about this?
now here we have : \[\sqrt{(a-5)^2}=\sqrt{81}\]
hence , \[(a-5) = 9 \]
hence \[(a = 9+5) \]
or that what satelite told u
