The above is a perfectly correct answer to the question as posed.
However, the question as written makes so little sense that I suspect this is another homework assignment that got slightly garbled in transmission. The original question was very likely : -
5a2 - 80 = 0. Solve for a.
If so, the answer is a = +4 or -4.
