Directions: Find the solution sets to the following quadratic equations. Hint: Remember to first put it into standard form if necessary. 1. 3x2 + 4x2 = 35 2. 3x2 – 28 = 2x2 + 33 3. x2 – 25 = 25 4. 2x2 – 30 = 70 5. 8x2 – 6x2 = 54 6. 3x2 – 6 = 34 – 2x2 7. x2 + 49 = 196 8. 5x2 – 40 = 100 9. 9x2 = 4x2 + 10 10. x2 – 4 = 80 11. x2 + 25 = 100 12. 2x2 + 7 = 67 13. (x2 + 22)= 16 14. (x + 5)2 = 23 15. (x – 4)2 = 11
