    Answer:

    (x-3) is the factor of polynomial x2 + 6x + 9

    and it’s zero is -3

    Step-by-step explanation:

    by solving it we get ;

    =

    x {}^{2}  + 6x + 9

    =

    x {}^{2}  + 3x + 3x + 9

    =

    x(x + 3) + 3(x + 3)

    =

    (x + 3) {}^{2}

    now, equating it with 0, we get

    =

    (x + 3) {}^{2}  = 0

    =

    x + 3 = 0

    =

    x =  - 3

    so, the factor is ( x + 3 )
