The equation √(x – 1) – 5 = x – 8 has the solution 2 and 5. But the valid solution for x will be 5.
The complete question is attached below.
The solution of the equation means the value of the unknown or variable.
The equation is given below.
√(x – 1) – 5 = x – 8
Add 5 on both sides, then we have
√(x – 1) = x – 3
Square on both sides, then
x – 1 = (x – 3)²
x – 1 = x² – 6x + 9
x² – 7x + 10 = 0
Then the factor of the equation will be
x² – 7x + 10 = 0
x² – 5x – 2x + 10 = 0
(x – 5)(x – 2) = 0
x = 5, 2
Then the valid solution will be 5.
