Quizplus · Accepted Answer

Since the equation has no constant term, we can simply take the square root of both sides to eliminate the squared variable. Taking the square root of both sides gives us x = ± √55. Since the answer choices are in the form (x, -x) or (x, 0), the only valid choice is (5, 0) since √55 is slightly larger than 7 and √55 ≠ 10.
