Answer 1

I know i'm late but I think this might be right, I don't know, I used a website-

Explanation:

When

√x-1

STEP

1

:

Isolate the square root on the left hand side

Radical already isolated

√x-1 = 0

STEP

2

:

Eliminate the radical on the left hand side

Raise both sides to the second power

(√x-1)2 = ()2

After squaring

x-1 =

STEP

3

:

Solve the linear equation

Rearranged equation

x -1 = 0

Add 1 to both sides

x = 1

A possible solution is :

x = 1

STEP

4

:

Check that the solution is correct

Original equation

√x-1 =

Plug in 1 for x

√(1)-1 =

Simplify

√0 = 0

Solution checks !!
