    First get them all on one side

    add 7x+60 to both sides

    0=x^2+17x+60

    now factor

    what 2 numbers mutltiply to get 60 and add to get 17?

    5 and 12

    0 = (x+5) (x+12)

    set each to zero

    0=x+5

    -5=x

    0=x+12

    -12=x

    the factored form is (x+5) (x+12) = 0

    the solutions are x=-12 and - 5
