    (x-k) = (x- (-2) = (x+2) use reminder theorem

    You can plug in just 2 as x according to the remainder theorem

    f(-2)= 4x3 - 6x2 + 3x + 1

    Actually, f(-2) = 4(-2)^3 - 6(-2)^2 + 3(-2) + 1

    -2 | 4 -6 3 1 -8 28 -62 4 -14 31 -61 i.e. \[\frac{4x^3-6x^2+3x+1}{x+2}=4x^2-14x+31-\frac{61}{x+2}\]
