You can put this solution on YOUR website!
You can graph the function and see when it drops below the x-axis.
+graph%28+300%2C+300%2C+-12%2C+12%2C+-12%2C+12%2C+%28x%2B10%29%2A%28x-6%29%29+

You can also choose a point in each of the three regions and test.
x%3C-10 x=-12, %28-12%2B10%29%28-12-6%29%3E0 -2%28-18%29%3E0 36%3E0 True, in the interval
-10%3Cx%3C6 x=0, %2810%29%28-6%29%3E0, -60%3E0 False, not in the interval
x%3E6 x=7, %287%2B10%29%2A%287-6%29%3E0,70%3E0 True, in the interval
