    x + 8 + x - 2 is equal to 2x + 6

    For example what if x = 1

    1 + 8 + 1 - 2 = 8

    2(1) + 6 = 8

    but

    x^2 + 6 = (1 x 1)+ 6 = 7

    or if x = 10 then x+8+x-2 = 26

    2x + 6 = 26

    x^2 + 6 = 106

    x + 8 + x - 2

    = ( x + x ) + ( 8 - 2 )

    = ( 2x ) + ( 6 )

    = 2x + 6

    - 6 = 2x

    2x = - 6

    x = - 3
