Which of the following is a solution to the equation above?

Question

Accepted Answer

Choice D is correct. A quadratic equation in the form , where a , b , and c are constants, can be solved using the quadratic formula: . Subtracting from both sides of the given equation yields . Applying the quadratic formula, where , , and , yields . This can be rewritten as . Since , or , the equation can be rewritten as . Dividing 2 from both the numerator and denominator yields or . Of these two solutions, only is present among the choices. Thus, the correct choice is D. Choice A is incorrect and may result from a computational or conceptual error. Choice B is incorrect and may result from using instead of as the quadratic formula. Choice C is incorrect and may result from rewriting as instead of .
