Directions: This is an activity to be completed with a partner. Each partner will take turns
picking a problem to solve using the Quadratic Formula. Once you have solved, you will find
your answer in the Tic-Tac-Toe grid and place either an “x” or “O” in the space. Play will
continue back and forth until all problems are completed or until someone wins! Work must
be shown on a separate sheet of paper and turned in with your Tic-Tac-Toe board.
1. 8x2 – 2x = 6
2. x2 + 19x = 40
3. x2 – 24x - 19 = 41
4. 2x2 – 6x - 12 = 0
5. 12x2 + 48x - 11 = 13
6. x2 – 13x + 30 = -10
7. 6x2 + 5x = 2
8. 3x2 + 7x = 2
9. x2 + 5x - 66 = 0
10. x2 – 28x = -120
11. x2 = 3x – 1
12. 6x – 5 = -x2
13. 3x2 = 2(2x + 1)
14. 2x(x – 1) = 3
15. x(x – 5) = -4
