2 answers

3 - 5 = -2

-2 / 8 = -0.25
You have now received 3 answers of -.25 from 3 different tutors.
That answer is correct according to the way you posted the question.

I also read it as:

((√3)^2 - 5)/8
= -2/8 = -1/4 or -.25

If you meant something different use brackets to establish the correct order of operations.
