arrow_back Return to Solving Quadratic Equations
To determine which of the given equations has one real solution, we can solve each of them. Let's begin with the equation in option I.
Because the square of real number cannot be negative, the equation does not have a real solution. Proceeding in the same way, we can solve the other equations.
Equation Simplification Root
I: No real root
II:
III: and
IV: and

As a result of our operations, the equation in option II has one real root.
