(A)
(B)
(C)
(D)
Formula Used:
Properties of equality:
If
Calculation:
Consider the equations are:
(A)
(B)
(C)
(D)
It is known that a quadratic equation with one real solution takes the form
Now, for equation (A).
Use property of equality in the above equation.
Simplify the above equation.
Since, the equation
Thus, the equation (A) does not have a real solution.
Now, for equation (B).
Use property of equality in the above equation.
Since, the equation
Thus, equation (B) has a real solution.
Now, for equation (C).
Use property of equality in the above equation.
Since, the equation
Thus, the equation (C) does not have a real solution.
Now, for equation (D).
Use property of equality in the above equation.
Since, the equation
Thus, the equation (D) does not have a real solution.
Hence, the required equation which has real solution is (B)
