If a quadratic function crosses the x-axis twice, it has two solutions. For a quadratic function in with discriminant , the following is true:
If , then the quadratic has two realsolutions
If , then the quadratic has one real solution
If , then the quadratic has no real solutions
Therefore, in order to have two solutions, a quadratic's discriminant must be larger than 0. The only two answer choices that satisfy this are 1001 and 1.
