The solution of a real-life equation should always be checked against—
- athe equation only
- bthe given conditions of the original problem (positivity, integrality, range)
- cnothing
- donly the textbook answer
ব্যাখ্যা
A real-life solution must satisfy the original problem's constraints—such as being positive, a whole number, or within an allowed range—not just the algebraic equation. Roots violating these conditions are discarded.
