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
