I never liked these because they never taught you how to do anything except guess and check.
(5-3)x2+8x(5-2) would work. First you simplify the stuff inside the parenthesis.
2x2+8x3
Multiply first
4+24
28

You don't want the 8x5 together, and for the last few terms, either ---x5-2 OR -----+24 look feasible. The first was eliminated quickly, leaving:
((5-3)x2) + (8x(5-2)) = (2x2) + (8x3) = 4 + 24 = 28

5-3x2+8x5-2; 28
(5-3)*2 + 8*(5-2) =28

I believe it would be: (5-3),2+8,(5-2) am I right? Do I win a prise?
