Question 348214: (5√x-2) - 3 = (√19x-29)

5 √[x - 2]) - 3 = √[19x - 29] square both side
25(x-2) – 30√(x-2) + 9 = 19 x – 29 add by -19x +30√(x-2) +29
6x-12 =30√(x-2) divide by 6
X -2 = 5√ (x-2) square both side
X^2 -4x + 4 =25x – 50
X^2 -29x +54=0
(x-27)(x-2) =0 → x= 27
We reject x = 2 because it does not satisfy the original radical equation.
The only answer is x = 27.
