Directions: Using the digits 0 to 9 at most one time each, fill in the boxes to so that the solutions are integers. Note that you can use a 05 to make a 5.
Hint
How could you find the equation if you already knew the solutions?
Answer
There are many answers including 3x^2 + 12x + 09 which has solutions of -1 and -3.

5/2 is not an integer
Nice catch, we updated the post. Thanks!
also, -7/2 and -5 are the solutions to that equation, and -7/2 is still not an integer
3x^2+18x+24 is a real solution
