x(x+10)(x-2)

Explanation:

First, you would divide x out of the whole expression to get
x(x^2+8x-20)
You would then factor x^2+8x-20. To factor it, you need to find two numbers that added together equal 8 and multiplied together equal -20. These two numbers would be 10 and -2, giving us
x(x+10)(x-2)
