I'm going to use > instead of ≥ since I don't want to copy paste every time.
10*8-3x+x2>x3+x2
PEMDAS
parenthesis exponent multiplication/division addition/substraction
[1]                       [2]                       [3]                        [4]
nothing for [1] [2]
[3] 10*8=80
so 80-3x+x2>x3+x2
now we have nothing so we will move things around
80-3x+x2-x3-x2>0
x2 cancel out
80-3x-x3>0
find x which is roughly 4.0770 and find the closest answer from that
