Answer:
{3+3i√7/-4, 3-3i√7/-4} is in fact correct, here is the explanation
Explanation:
By replacing y with 0 in
, you can use the quadratic formula
and plug in the values a = -2, b = -3, and c = -9 to end up with your answer. If you are confused as to i showed up, it is because in the equation, the discriminant is 9 + 8 * -9 or -63. if the discriminant is a negative number, there will be no real solutions, and only imaginary ones.
