    x = 0 or x = 3

    Step-by-step explanation:

    if f (x) = g (x) then - x2 + 4x + 1 = x + 1

    add the like terms

    -x^2 + 3x = 0

    -x (x-3) = 0 then x is either 0 or 3

    The 2 solutions are 0 and 3,

    Step-by-step explanation:

    - x2 + 4x + 1 = x + 1

    -x^2 + 3x = 0

    x (-x - 3)

    x = 0 or - x - 3 = 0 which gives x = 3.
