Use the quadratic formula to solve the equation. If the solutions involve square roots, give both the exact and approximate solutions. 5x2 -3x-7=0 A. The solution(s) involve(s) square roots. The solution(s) is/are x = 3+4/149 3-4/149 10 10 ' (Type an exact answer, using radicals as needed. Use a comma to separate answers as needed.) O B. The solution(s) do(es) not involve(s) square roots. The solution(s) is/are x = (Simplify your answer. Use a comma to separate answers as needed.) () C. There are no real solutions. What are the approximate solutions? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The exact solution(s) involve(s) square roots. The approximate solution(s) is/are x = (Round to three decimal places as needed. Use a comma to separate answers as needed.) B. The solution(s) do(es) not involve(s) square roots, so there is no approximate solution. C. There are no real solutions
