    Answer:

    \huge\boxed{\purple{hello}}\boxed{\pink{dude}}

    Given that g(x)= -2

    Step-by-step explanation:

    p(x)=3x²+13x+14

    p(-2)=3(-2)²+13(-2)+14

    p(-2)=12-26+14

    p(-2)=26-26

    p(-2)= 0

    So,it proves that 0 is the ANSWER if g(x) is-2

    Answer:

    x=-2

    p(x)=3x²+13x+14

    p(-2)=3(-2)²+13(-2)+14

    =3(4)-26+14

    =12-26+14

    =26-26

    =0

    So x=-2 is a solution
