    another short method
    we can break the polynomial into multiplication of 2 quadratic and find the coefecients of these 2 quadratic then check D by range of A

    a^2+3ax+2x^2=x^4+x^3
    Now make LHS perfect square by adding 9x^2/4 on both side
    (a+3x/2)^2+2x^2
    =x^4+x^3+9x^2/4
    (a+3x/2)^2 =(x^2+x/2)^2
    a+3x/2=+-(x^2+x/2)
