KnowledgeBoat · Accepted Answer

(i) Given, Substituting x = 2 in the LHS of the given equation, we get: ∴ 2 is a root of the given equation. Substituting x = -3 in the LHS of the given equation, we get: ≠ ∴ 3 is not a root of the given equation. Hence, 2 is a root but -3 is not a root of the given equation. (ii) Given, Substituting x = 5 in the LHS of the given equation, we get: ∴ 5 is a root of the equation Substituting x = in the LHS of the given equation, we get: ∴ is a root of the equation Hence, both 5 and are roots of the given equation.
