x + 2 x - 5 x + 9 = 0 What is a positive solution to the given equation?

Question

Accepted Answer

Choice C is correct. Applying the zero product property to the given equation yields three equations: x + 2 = 0 , x - 5 = 0 , and x + 9 = 0 . Subtracting 2 from both sides of the equation x + 2 = 0 yields x = - 2 . Adding 5 to both sides of the equation x - 5 = 0 yields x = 5 . Subtracting 9 from both sides of the equation x + 9 = 0 yields x = - 9 . Therefore, the solutions to the given equation are - 2 , 5 , and - 9 . It follows that a positive solution to the given equation is 5 . Choice A is incorrect and may result from conceptual or calculation errors. Choice B is incorrect and may result from conceptual or calculation errors. Choice D is incorrect and may result from conceptual or calculation errors.
