Question

√6x-14-√5x-9+√5-x=0 помогите

Answer 1

√(6x - 14) + √(5 - x) = √(5x - 9)
6x - 14 + 2√(6x - 14)(5 - x) + 5  - x = 5x -  9 
5x - 9 + 2√(6x - 14)(5 - x)  = 5x - 9 
2 √(6x - 14)(5 - x)  = 0 
4 (6x - 14)(5 - x)  = 0  / : 4
(6x - 14)(5 - x)  = 0 

1) 6x - 14 = 0 
6x = 14 
x = 7/3

2) 5 - x = 0 
- x = -  5
x = 5 

Ответ
 5 ; 7/3
