| Written Problems |
| 21. Solve (x + 1)(x + 6) = 0.
Show all work. x = -1, -6 |
| 22. x2 - 13x + 12 = 0.
Show all work. (x - 12)(x - 1) = 0 so x = 12,1 |
| 23. Solve x2 -
10x = 0. Show all work. x(x - 10) = 0 so x = 0, 10 |
| 24. Solve (3x - 5)(4x -
7) = 0. Show all work. x = 5/3,7/4 |
| 25. Solve (3x + 5)(4x + 7) = 0.
Show all work. x = -5/3,-7/4 |
| 26. Written Problem: Solve (2x - 3)(2x
- 5) = 0. Show all work. x = 3/2, 5/2 |
| 27. Written Problem: Solve (2x - 31)(2x
- 51) = 0. Show all work. x = 31/2, 51/2 |
| 28. EC Written Problem: Solve x2
+ 12x + 11 = 0. Show all work.(x + 11)(x + 1) = 0 so x = -11,-1 |
29. EC Written Problem. Convert to
decimal notation. 8.96x10-14 . Show all work.
0.0000000000000896.
