They want you  to  find the x values that make

 

x^2 - 6x  + 8  =    x - 2

 

Pick  a few values for x

                   f(x)                                g(x)

x = 0       0^2 - 6(0) + 8  = 8          0  - 2    =  -2       not true

x  =1       1^2  - 6(1) + 8  = 3         1 - 2  =  - 1         not true

x = 2        2^2 - 6(2) + 8 = 0           2 - 2  =  0         true  

x = 3       3^2  - 6(3) + 8 = 8           3 - 2  = 1          not true

x  = 4      4^2  - 6(4) + 8 = 0           4 - 2  =  2         not true

x = 5       5^2  - 6(5) + 8 = 3           5 - 2  = 3          true

 

So  x  = 2   and x = 5   are the solutions
