Question

1. х + 2,6 = 3,4
2. 6х = 1,2
3. 3х – 8 = 15
4. 2х + 3 = 5х -27
5. 5(х – 2) + 3х = 6
6. 6х – 2(4х – 1) =7
7. х -5(х + 4) = 2(х – 8) + 8
8. х - х/8=7/16
9. х/11+х=24/11
10. 11/(х+3)=11/2
11. (х+5)/(х+15)=3/4
12. (х-7)/(х-15)=3
13. х2 = 4
14. х2 – 8х = 0
15. х2 = 3х
16. х2 – 10х + 25 = 0
17. х2 + 5х – 6 = 0
18. х2 – 2х – 48 = 0
19. – х2 + 2х + 3 = 0
20. 2х2 + 5х – 3 = 0
21. 3х2 – 2х + 4 = 0
22. х2 + 8х = 9
23. (2х - 3)(х + 5) = 0
24. (х2 – 1)(5х + 8) = 0
2 часть
1. х4 – 10х2 + 9 = 0
2. (2х – 5)2 + 3(2х-5) – 4 = 0
3. х3 – 2х2 + 2х – 4 = 0
4. (х + 3)(х – 5) + (х + 3)(х – 3) = 0
5. (х + 4)2(х – 5) + (х + 4)(х – 5)2=0
6. (х^2+8х+12)/(х+6)=0
