MATHEMATICS 17 EXERCISE SET 2 I. Find the solution set of the following. 1. 2 x + 2 = - x x 2 + 5 x + 6 2. 2 x + 1 = 4 - 2 x x + 1 3. 5 2 y - 6 = 10 - y y 2 - 6 y + 9 4. x 2 + 2 x - 1 = 0 5. ( x + 2 ) ( x - 1 ) = 4 6. 4 - 9 x - 3 x - 2 = 0 7. 3 x + 6 = x + 3 + 1 8. 2 x + 11 + 1 = 5 x + 1 9. ( x 2 - x - 5 ) 2 - ( 4 x 2 - 4 x - 20 ) - 21 = 0 10. ( x + 1 ) 4 + 4 ( x 2 + 2 x + 1 ) = 5 11. 8 ± 2 x 2 + 1 2 x ² 2 - 30 ± x + 1 2 x ² + 27 = 0 12. | 3 x - 5 | ≤| 2 x + 7 | 13. ³ ³ ³ ³ 4 x - 1 3 x + 2 ³ ³ ³ ³ 1 14. 2 x x + 1 ≤ - 3 15. ( y - 3 ) ( y 2 + y - 2 ) y 2 + 4 y + 3 0 16. x + 3 y = - 11 2 y - z = - 11 3 x + 2 z = 9 17. 2 x - 3 y - 5 z = 4 x + 7 y + 6 z = - 7 7 x - 2 y - 9 z = 6 18. 5 x + 3 y = 2 2 x - 7 y - 5 z = 4 3 x + 11 z = 14 19. ´ x 2 - 2 x + y 2 + 2 y = 7 x - y = - 1 20. ´ x 2 + y 2 = 36 x 2 - 14 x + y 2 + 4 y + 49 = 0 II. Do as indicated. 1. If f ( x ) = 2 x + 1 and ( f g ) ( x ) = 3 - 2 x , find g ( x ) . 2. The midpoint of
