Solve: x= sqrt(10x-4-2)

Answer 1

The last time I checked, -4 -2 = 6.
Check to make sure you did not omit some parentheses that would change the maning of what you wrote

Square both sides of the equation and solve the resulting quadratic.

x^2 - 10x +6 = 0

Answer 2

The problem is solve x= sqrt10x-4-2
