    Answer:

    Hi the answer is -a

    Step-by-step explanation:

    There is a formula which is

    a + b =  \frac{ - coefficient \: of \:  x \: term}{coefficient \: of \:  {x}^{2}  \: term}

    So according to the formula coefficient of

     {x}^{2}

    is 1 and coefficient of x term is a

    so now the sum of roots= -a/1

    So now the answer is -a
