Evaluate the discriminant and use it to determine the number of real solutions of the equation. If the equation does have real solutions, tell whether they are rational or irrational. Do not actually solve the equation. 9x- + 18x +9=0 . . . . . O - b+vb- - 4ac O b- + 4ac b- - 4ac O -b- vb - 4ac The discriminant is 0 (Simplify your answer. Type an integer or a simplified fraction.) Determine the number of real solutions of the equation. If the equation does have real solutions, tell whether they are rational or irrational. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The equation has real rational solution(s). (Type a whole number.) O B. The equation has real irrational solution(s). (Type a whole number.) O C. The equation has no real solutions
