  1. What is the positive solution to 3x2– 2 = 10?

  2. What is the negative solution to 3x2 – 2 = 10?

  3. 5(x2 + 5) = 90

  4. x2 + 4x2 = 20

  5. 5x2– 18 = -23

  6. (x – 3)2 = 25

  7. (x + 2)2 = 36

  8. (x + 7)2 = -1

  9. (x + 3)2 = 12

  10. 2(x + 2)2 = 8

  11. 3(x – 1)2 = 27

  12. 2(x – 1)2 + 5 = 13

  13. –3(x + 1)2 - 4 = 8

  14. –2(x + 3)2 = -12

  15. You want to build a fence around a square garden that covers 506.25 ft2. How many feet of fence will you need to complete the job?

  16. The formula A = 6s2 will calculate the surface area of a cube. Suppose you have a cube that has a surface area of 216 in2. What is the length of each side?

  17. You drop a pencil out of a window that is 20 ft above the ground. Use the formula S2= 64d, where Sis speed and d is distance fallen, to calculate the speed the pencil is traveling when it hits the ground.

  18. You want to construct a circular fish pond in your garden. You want the pond to cover an area of 300 ft2. What is the radius of the pond?

  19. During the construction of a skyscraper a bolt fell from 400 ft. What was the speed of the bolt when it hit the ground? Use S2= 64d.

  20. . The elasticity coefficient e of a ball relates the height r of its rebounds to the height h from which it is dropped. You can find the elasticity coefficient using the function What is the elasticity coefficient for a tennis ball that rebounds 3 ft after it is dropped form a height of 3.5 ft?
