Without the specific equation, it is impossible to calculate the exact solutions. However, the quadratic formula always yields two solutions (real or imaginary) for any quadratic equation. Therefore, we can eliminate A, B, and D as all of them only have two real solutions. The only choice left is E, which has two real solutions, x = 5 and x = 2.
