Answer:
1001
1
Step-by-step explanation:
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 real solutions - 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.
-2 * 2n -2 equals -4n + 4 > 18n -3n
