Math 100 Test 2 6 pts each (4 pts free!) Feb 13, 2002

Simplify:

1. 1.

2. 3x - 2{4x -3(1 - 2x)}

3.

4. 8p - 4[3p + 2{3(p - 9) - 4 ( p + 1) }]

5. (3x² + 5x - 3) - (2x² - 8x - 1) + 2(x² + x - 7)

6. (3x - 2y²)(3x +2y²)

7. (2x² +4x -5)(2x² -3x + 2)

8. (-2a³y)(3a² y⁴)²

9. (2x³ +3)²

Solve for x:

10. 2x - 5 = 6x - 9

11. -3(x - 1) + 4x =2(x - 3) - (x - 9)

12.

13. b - ax = c

14. ax + 3x +b = c

15. Solve for x: give answer in interval notation.

3 - 2(x - 3) ≤ 4x

16. Solve for x: graph the solution on a number line.

-5 < 2(3 - 2x) ≤ -2
