Question

Identify the first step to solving the following equation.

Answer 1

B, so that later you can square both sides to remove square root

Answer 2

im not gonna tell you the answer...but i am going to tell you HOW to solve this and then you can think for yourself which is which ;)
\[\sqrt{6x - 4} - \sqrt{2x+10} = 0\]
\[\sqrt{6x - 4} = \sqrt{2x + 10}\]
\[(\sqrt{6x - 4})^2 = (\sqrt{2x + 10})^2\]
\[6x - 4 = 2x + 10\]
\[6x - 2x = 10 + 4\]
\[4x = 14\]
\[x = 14/4\]
\[x = 7/2\]

Answer 3

so what do you think is the first step i did? ;)

Answer 4

Square both sides('=

Answer 5
