B Correct answer
Explanation

Set 4u^2 + 8u = 0. Factor out 4u: 4u(u + 2) = 0. The roots are u = 0 and u = -2.

AI explanation

To find the zeros of the polynomial 4u^2 + 8u, set it equal to zero and factor out the common term 4u. This gives 4u(u + 2) = 0. Equating each factor to zero provides the roots u = 0 and u = -2.
