Which of the following is a valid step in the solution of 4sqrt2x+4sqrt (x) + 3=0

4-sqrt (x) - 3=0 One solution was found : x = 1

Radical Equation entered:

4-√x-3 = 0

Step by step solution : Step 1 : Isolate the square root on the left hand side:

Original equation

4-√x-3 = 0

Isolate

-√x = - 4+3+0

Tidy up

√x = 1

Step 2 : Eliminate the radical on the left hand side:

Raise both sides to the second power

(√x) 2 = (1) 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, root isolated, after tidy up

√x = 1

Plug in 1 for x

√ (1) = 1

Simplify

√1 = 1

Solution checks!

Solution is:

x = 1
