Since $ t = \sqrtu \geq 0 $, and all roots are real and non-negative, each root $ t $ corresponds to a non-negative $ u = t^2 $. Therefore, the sum of the values of $ u $ is not directly the sum of $ t^2 $, but the question asks for the **sum of the roots of the original equation in $ u $**, which are $ t^2 $, so we compute: - Veritas Home Health
