Given a quadratic equation in the form ax^{2} + bx + c. The task is to find the floor of roots of it. For example, floor of 5.6 is 5.

Input:
First line of input contains an integer, the number of test cases T. Each test case should contain three positive numbers a, b and c in the same line seperated by space.

Output:
If roots of equations exists, then print the two roots separated by space (Higher valued root should be printed before lower valued). Else if a = 0, then print "Invalid" as equation is not quadratic. If roots are imaginary, then print "Imaginary"

Constraints:
1 <= T <= 50
-10^{3} <= a <= 10^{3}
-10^{3} <= b <= 10^{3}
-10^{3} <= c <= 10^{3}

Example: Input:
3
1 -2 1
1 -7 12
1 4 8

Output:
1 1
4 3
Imaginary

Explanation:
Testcase 1: Roots of equation x^{2} - 7x + 12 are 4 and 3. Testcase 3: Roots of equation x^{2} + 4x + 8 are imaginary since it's discriminant is less than 0.
