    Find the zeros of the function...

    Find the zeros of the function h(x)= x^2 + 23x + 60 by factoring.
    __

    I know I need to set the problem to h(x) = x^2 + 23x + 60 = 0

    But I'm not quite sure what to factor out.

    you can factor it as (x + a)(x + b)

    where a and b are two numbers such that, when you multiply them you get 60 and when you add them you get 23

    (x-20)(x-3)

    Would work, thanks.

    actually, no. if you add -20 and -3 you get -23 which is not the coefficient of the middle term
