Sqrt 6x+1=x-1
I don't know how to attempt this problem do I square it? I did that and them I end up with things I can't simplify?

Square both sides:
6x + 1 = (x-1)^2
Expand:
6x + 1 = x^2 - 2x + 1
Combine like terms:
x^2 - 8x = 0
Factor:
x(x-8) = 0
Solve for x:
x = 0 and x = 8
6x + 1 = (x-1)^2
Expand:
6x + 1 = x^2 - 2x + 1
Combine like terms:
x^2 - 8x = 0
Factor:
x(x-8) = 0
Solve for x:
x = 0 and x = 8

√(6x+1) =x-1
Squaring both sides we get:
(6x+1)=(x-1)²
(6x+1)=x²-2x+1
6x+1-x²+2x-1=0
-x²+8x=0
x²-8x=0
x(x-8)=0
x=0 or x=8
Squaring both sides we get:
(6x+1)=(x-1)²
(6x+1)=x²-2x+1
6x+1-x²+2x-1=0
-x²+8x=0
x²-8x=0
x(x-8)=0
x=0 or x=8

Sqrt (6x + 1) = x - 1
6x + 1 = x^2 - 2x + 1
x^2 - 8x = 0
x(x - 8) = 0
Solutions:
x = 0
x = 8
6x + 1 = x^2 - 2x + 1
x^2 - 8x = 0
x(x - 8) = 0
Solutions:
x = 0
x = 8
