    First, we must factor the equation. To do so, we need to find factors of 30 that also add up to eleven. 5 and 6 will do the trick. The equation factors as such:

    (x+5) (x+6). Using the zero product property, x can equal either - 5 or - 6, either of which will make the equation equal zero.

    First you need to factor the equation

    x^2+11x+30

    You can do this by asking yourself:

    "What multiplies to 30 but adds up to 11?"

    In this case, 6 and 5 work

    Factor:

    (x+6) (x+5)

    If you were to foil the factored form you would get

    x^2+11x+30

    The Zero Product Property is where you set your factored forms to zero like so:

    x+6=0

    x+5=0

    And then you would solve for x

    Final answer:

    x=-6 or x=-5
