Solution:
we have been asked to solve the given equation.
The given equstion is [tex] 5a^2-44=81 [/tex]
This can be solved as below
[tex] 5a^2-44=81\\
\\
\text{Add 44 on both the sides we get}\\
\\
5a^2-44+44=81+44\\
\\
5a^2=125\\
\\
a^2=25\\
\\
\text{Take square root on both the sides we get}\\
\\
a=\pm 5\\ [/tex]
Hence the solution of the given equation is 5, -5
