To solve for the roots of the function, we can use the Rational Root Theorem. The possible rational roots are all factors of 20 (the constant term) divided by all factors of 1 (the leading coefficient). This gives us the possible rational roots of ±1, ±2, ±4, ±5, ±10, and ±20. We can test these roots using synthetic division or substitution to find that -2 and 10 are roots of the function. Therefore, the answer is x = -2,10 or choice D.
